When all efforts in rest, physical therapy, and pain medications fail to ease hip pain, a cortisone shot in the hip becomes the logical next step. Given the deep location of the hip joint within the thick layers of muscles in the body, this procedure proves to be more difficult than injecting the knee or the shoulder joint. This manual gives detailed information about this procedure and its effectiveness.
Quick Answer:
A cortisone shot in the hip involves the delivery of a numbing agent and steroid to your joint to minimize inflammation. You experience the immediate effects due to the numbing agent within a couple of hours, while the steroid will take 2 to 7 days before its effects manifest. You will experience the peak of the effect in 1 to 2 weeks and have pain relief for 6 to 12 weeks after that. 75% of patients experience good pain relief after one month.
Simple Breakdown:
- What it does: The hip cortisone shot works by minimizing joint inflammation.
- Immediate effect: It is achieved through the numbing effect that comes about a couple of hours later.
- When does the steroid start? It takes 2 to 7 days to begin working.
- When does the peak effect come? After 1 to 2 weeks.
- How long does the effect last? Pain relief can last for 6 to 12 weeks.
What Is a Cortisone Shot in the Hip?
A cortisone shot in the hip area is a specific injection that immediately relieves inflammation and alleviates joint pain.
- An injection of a corticosteroid within the hip joint space (Intra-articular).
- Together with a local anesthetic agent (either lidocaine or bupivacaine).
- The hip joint is one of the most deeply seated joints in the body,
- Imaging guidance cannot be done without.
- It is performed completely in an outpatient setting; no hospital admission or general anesthesia required.
- Also known as: cortisone hip injection, hip joint injection, intra-articular cortisone hip injection, hip joint steroid injection.
What Conditions Does a Cortisone Shot in the Hip Treat?
The cortisone injection in the hip decreases the inflammation that causes the pain, thereby giving temporary relief from different joint problems.
- Hip Osteoarthritis: Helps to alleviate pain and inflammation that occurs due to the breakdown of cartilage in the joint.
- Hip Bursitis: Treats inflammation of the fluid-filled sac that cushions the outside or rear part of the hip joint.
- Iliopsoas Bursitis & Tendinitis: Treats inflammation of deep front-hip and groin areas due to inflammation of the tendons and bursa sacs.
- Hip Labral Tear: Treats inflammation and pain occurring around the joint ring; however, it is not able to physically repair the tear.
- Femoroacetabular Impingement (FAI): Treats front-hip pain due to abnormal bone friction inside the socket.
- Rheumatoid Arthritis: Helps to treat joint inflammation caused by the autoimmune response.
- Snapping Hip Syndrome: Treats pain and irritation due to the catching and rubbing of tendons over the inflamed joint.
Who Is a Good Candidate for a Hip Cortisone Injection?
You qualify for this procedure if you have severe pain in the hip area due to inflammation or arthritis, and your condition hasn’t responded to conservative therapy.
Good candidates:
- The diagnosis is confirmed by imaging studies (X-rays or MRI showing osteoarthritis, bursitis, or labral tears).
- Pain significantly affects movement, climbing stairs, sleep, or activities of daily living.
- Has undergone treatment with physical therapy, NSAIDs, and exercise modifications for 4-6 weeks.
NOT recommended for:
- Hip joint infection
- Corticosteroid allergy or local anesthetic allergy (Lidocaine/Bupivacaine)
- The patient has had 3-4 hip joint injections within the same year.
- Poor-quality hip joint cartilage with poor bone quality.
Why the Hip Requires Imaging Guidance: And Why It Matters
Thick muscular layers cover the hip area (gluteus maximus, gluteus medius, iliopsoas), which makes blind injections impossible. The research shows that:
- Accuracy of injection without imaging: 60 to 80% for the hip
- Accuracy of injection with fluoroscopy or ultrasound: 95%+
- Incorrect injection: Medication will be injected into the muscle or bursa instead of the joint; thus, the procedure is useless
- Ultrasound guidance: Visualization of soft tissues in real time. No radiation. Effective for trochanteric bursitis and superficial structures of the hip joint.
- Fluoroscopy (live X-ray) guidance: Most effective for intra-articular hip joint. Contrast dye injection to verify if the needle is correctly placed before medication injection.
The Cortisone Injection in Hip: Step-by-Step Procedure
This is a quick 10-minute procedure where the doctor numbs your skin and uses a scan to guide medicine directly into your hip joint.
Before:
- Hip Injections Don’t Require Any Fasting
- Make Your Doctor Aware of Any Blood Thinners, Diabetes, or Allergies to Steroids or Local Anesthesia
During:
- Patient Positioning: Supine (on the back) if the injection is in the joint; lateral (on the side) if bursitis
- Sterilization: Sterilization with antiseptic solution (Betadine or chlorhexidine)
- Anesthesia Injection: Anesthesia injection into the skin and subcutaneous tissues to numb the tract
- Imaging: Activating fluoroscopy or ultrasound for imaging of the procedure
- Needle Advancement: Needles are advanced to the capsule of the hip joint and are monitored under imaging
- Contrast: A few drops of contrast media are injected if fluoroscopy is used, before confirmation of intra-articular position
- Injection: A combination of cortisone and anesthesia injections (5-10 seconds)
- Completion of Procedure: Withdrawal of needles; sterile dressing
- Observation: The patient is observed for 15-30 minutes
Total time: 20–30 minutes
Setting: Outpatient office, pain management clinic, or interventional radiology suite
How Long Does a Cortisone Shot in the Hip Take to Work?
The cortisone shot in the hip timeline has two distinct phases most patients do not expect:
| Phase | Timeframe | What Happens |
|---|---|---|
| Local anesthetic effect | First 15–20 minutes | Immediate but temporary relief—the numbing agent |
| Anesthetic wearing off | Hours 4–6 | Pain returns to baseline or feels slightly worse |
| Cortisone onset | Days 2–7 | Anti-inflammatory effect begins; gradual improvement |
| Full cortisone effect | Weeks 1–2 | Most patients notice peak improvement |
| 1-month mark | ~Day 30 | ~75% of patients report meaningful relief |
| 3-month mark | ~Day 90 | ~33% of patients still experiencing relief |
Note: Do not evaluate the injection within the first 48 hours since the temporary pain resulting from anesthesia is not an indication of failure.
How Long Does a Cortisone Shot in the Hip Last?
You will usually experience pain relief from the injection for one to six months.
- Mean of published studies: 6.7 weeks of relief.
- Range in clinical practice: 6 weeks to 6 months, depending on the patient.
- Shortening the relief time: More advanced OA, active patient, repeat injections.
- Extending the relief time: Early OA, moderate activity level, first or second injection.
- Long-term effects: Decreased relief from each new injection as the joint deteriorates further.
Cortisone Shot in Hip: Day-by-Day Recovery Guide
The guide outlines the expected experiences for every day after your injection until your hip has healed and you have recovered from the pain.
| Timeframe | What to Do / What to Expect |
|---|---|
| Day 1 (day of injection) | Rest. Light walking is fine. Avoid driving if lidocaine causes temporary numbness. |
| Days 1–2 | Anesthetic wears off; the hip may feel the same or slightly more sore than before. Normal. |
| Days 2–7 | Cortisone activating. Gradual reduction in pain and stiffness; most patients notice by day 3–5. |
| Weeks 1–2 | Full cortisone effect. Most patients are at peak improvement. |
| Month 1 | ~75% are still benefiting. Good window to start or intensify physical therapy. |
| Month 3+ | ~33% are still benefiting. If the effect has worn off, discuss next steps with your doctor. |
Activity restrictions after hip cortisone injection:
- Light walking: Same day, fine
- Stairs at normal pace: Next day
- Low-impact exercise (cycling, swimming): 48 hours after
- High-impact activity (running, sports): Wait 1 week minimum
- Ice: 15–20 minutes several times daily for the first 2–3 days to manage any flare
Diagnostic Value: The Diagnostic Numbing Test (Hip vs. Lumbar Spine)
One crucial aspect often overlooked is the diagnostic value of a cortisone shot in hip procedures. Because the lumbar spine (L4-S1 compressed nerves) may cause pain directly in the groin and buttocks, it is hard to determine if the pain begins in the hip or the low back.
When the local anesthesia (lidocaine or bupivacaine) is introduced into the joint of the hip, the level of the patient’s pain is observed for the first 15-30 minutes:
- 80%+ Pain Relief in First 30 Minutes: Confirms the hip joint is the true primary source of pain.
- Little to No Relief in First 30 Minutes: Indicates the pain may be coming from referred lumbar spine issues or surrounding nerves rather than intra-articular hip pathology.
Critical 90-Day Surgical Washout Window Before Hip Replacement
If you are considering eventual joint replacement surgery, timing your cortisone injection in hip care is critical.
- The 90-Day Rule: You must wait at least 90 days (3 months) after receiving a hip cortisone injection before undergoing Total Hip Arthroplasty (THA).
- Infection Risk: Injecting corticosteroids suppresses local joint immunity. Undergoing surgery within 3 months of an intra-articular steroid injection significantly increases the risk of deep prosthetic joint infection (PJI) post-surgery.
72-Hour Infection Prevention Restrictions & Activity Protocols
While basic guidelines recommend brief rest, strict infection-control protocols require specific precautions following a deep joint injection:
- After 24 Hours: It is safe for you to take a short shower.
- For 72 Hours (3 Days): You should avoid coming into contact with water. You should not swim in pools, bathe in tubs, take dips in hot tubs, or get into the sea.
Why? Because the small opening created by the injection needle takes 3 days to close. Any kind of exposure to water during this period will introduce dangerous bacteria through that opening into your muscle tissue.
- Driving Prohibitions: Driving is strictly prohibited on the day of the procedure if local anesthetic causes any temporary numbness, motor weakness, or altered reflexes in the leg.
Diabetic Care Protocol: Managing Blood Sugar Spikes
For those with either Type 1 or Type 2 diabetes, the corticosteroid injection can lead to systemic absorption as follows:
- Increased Blood Glucose: The patient can expect increased levels of blood glucose, within the range of 200 to 300+ mg/dL for 24 to 72 hours after the procedure.
- Steps to take: The diabetic patient is supposed to monitor blood glucose levels frequently (every 4 to 6 hours) for 3 days after the procedure and consult their endocrinologist/physician.
Success Rate of Cortisone Injections in the Hip
What the clinical data actually shows:
- 80% experience pain relief to varying degrees
- 75% experience significant relief after 1 month
- 33% experience significant relief after 3 months
- 20% are non-responders (no response at all), suggesting that the pain is likely not coming from the hip joint but possibly from another location, such as the spine
- Greater success with: Early stages of OA, proper diagnosis through imaging, proper placement of injection
Side Effects of a Cortisone Shot in the Hip
Common (expected, temporary):
- Cortisone flare: Temporary increase in hip pain for 12–48 hours before improvement begins
- Facial flushing: On the day of injection (from systemic cortisone absorption)
- Blood sugar elevation: For 1–3 days in diabetic patients
- Mild bruising or swelling: At the needle entry site
Less common:
- Temporary weakness in hip or leg muscles from local anesthetic spreading
- Skin thinning or depigmentation at the injection site with repeated injections over time
Rare but call your doctor if:
- Increase in Pain: Your hip pain becomes significantly more severe after 3 days rather than improving.
- Fever: Body temperature rises above 100.4°F (38°C).
- Change in Skin Appearance: Redness, warmth, and/or swelling around the area continues to worsen after 2 days.
How Many Cortisone Shots Can You Have in the Hip Per Year?
For this reason, most physicians advise receiving no more than three to four cortisone injections into the same hip annually.
- Clinical standard protocol: Max of 3- 4 shots per year per joint
- Minimum interval between injections: 12 weeks (6 weeks by some practitioners)
- Reason for the limitation: The more cortisone is used, the more quickly cartilage is broken down, particularly in the hip joint, which bears body weight
- Indications that the limits have been reached: If two consecutive shots provide fewer than 6 weeks of relief, the cortisone is ineffective, and further treatment must be considered.
Cortisone Failure Protocol: Transitioning to Regenerative Options
When a cortisone shot in hip tissue stops providing meaningful relief, repeating injections can degrade remaining cartilage. At this stage, transitioning from temporary anti-inflammatory suppression to biologic tissue support is recommended.
| Option | Onset | Duration | Repairs Hip? | Covered by Insurance? |
|---|---|---|---|---|
| Cortisone injection | 2–7 days | 6–12 weeks | No | Usually yes |
| PRP injection | 2–6 weeks | 6–18 months | Partially | Usually no |
| Stem cell / bone marrow | 4–8 weeks | 12–24+ months | Yes | Usually no |
| Hip replacement surgery | Recovery 6–12 weeks | Long-term | Yes (artificial joint) | Usually yes |
At Conscious Regenerative Medicine, patients who have exhausted cortisone benefits are evaluated for PRP and regenerative options before considering surgical referral.
Key Takeaways
- Imaging Guidance Is Necessary: The hip joint is too deep to inject blindly; ultrasound or fluoroscopic guidance is required.
- Two-Phase Relief: Immediate anesthetic effect (hours) followed by cortisone onset (days 2-7).
- Success Rates: 75% of patients have meaningful relief at 1 month; this drops to 33% at 3 months. Average relief lasts 6–12 weeks.
- Strict Limitations: No more than 3-4 injections annually so as not to hasten cartilage deterioration in a weight-bearing joint.
- Critical Precautions: Maintain a gap of 90 days between a cortisone shot and hip joint replacement surgery, observe 72 hours of water immersion limitations, and monitor diabetic blood sugar fluctuations.
Conclusion
Hip pain and inflammation can be quickly resolved with a cortisone shot in the hip, but they are only temporary treatments without offering a cure. The doctor will have to scan you, ensure that the injection is given in the precise location, keep track of the frequency of your shots over a year, and postpone hip surgery for 90 days.
At Conscious Regenerative Medicine, we prioritize precision diagnostics and comprehensive joint care.
Our clinical team utilizes real-time image guidance for every hip procedure and offers advanced regenerative alternatives such as PRP and cellular therapies when cortisone is no longer providing durable relief.

FAQ’s
What is a cortisone shot in the hip?
The treatment involves the injection of a corticosteroid and an anesthetic into the hip joint or bursa through imaging technology to alleviate inflammation and pain.
Does a cortisone shot in the hip hurt?
Most patients experience only minor pressure. The provider uses a local anesthetic to numb the skin and subcutaneous tissue before inserting the syringe.
How long does a cortisone shot in the hip take to work?
Although the local anesthesia provides temporary relief for several hours, it takes between 2 and 7 days for the cortisone to start bringing down the swelling, with its full effects kicking in after 1 to 2 weeks.
How long does a cortisone shot in the hip last?
Duration ranges from 6 weeks to 6 months, with the mean duration found to be about 6.7 weeks based on clinical research findings, which depend on the level of joint degeneration.
Can I walk after a cortisone injection in the hip?
Yes, light walking is allowed right away after the injection. But it is best not to do any exercise that involves impact for at least 48 hours to 1 week.
Why does my hip hurt more after a cortisone shot?
This is referred to as a “cortisone flare” and occurs in about 15% of cases when the anesthetic is absorbed before the steroid becomes active. It results in irritation that lasts 12 to 48 hours and can be treated with cold packs.
How many cortisone shots can you have in the hip?
Medically, it is advised that up to 3 to 4 injections per year should be administered to the same joint at intervals of 12 weeks to avoid the breakdown of cartilage.
What is the success rate of cortisone shots in the hip?
About 80 percent of people show a significant reduction in pain, with 75 percent retaining their relief after one month and 33 percent after 3 months.
