Do Hip Injections Hurt? Pain Levels & What to Expect

Most people rate the pain of an ultrasound-guided hip injection somewhere around 2 to 3 out of 10 on a standard pain scale, which puts it roughly on par with a routine blood draw or a flu shot into a deeper target. The actual needle stick tends to be the briefest part of the experience. What surprises many patients is not how much it hurts during the procedure but the temporary soreness that can follow in the first day or two afterward. The full picture of what to expect depends on the type of guidance used, what substance is being injected, and your own anxiety level going in.

What the Needle Actually Feels Like

The hip joint sits deeper than the knee or shoulder, so the needle has to travel through more tissue to reach the joint capsule. That depth is part of what makes the prospect intimidating. But the soft tissue the needle passes through has relatively few pain-sensing nerve endings compared to, say, the palm of your hand or the sole of your foot. Most patients describe a pressure sensation as the needle advances, a brief sting when it enters the joint capsule, and then a feeling of fullness as the medication is deposited.

One orthopedic study measuring pain during ultrasound-guided hip injections found an average pain score of just 1.9 out of 10, with the entire procedure taking about two and a half minutes from start to finish.¹ That score is lower than many people expect. Research on joint injections generally shows a gap between how much pain patients anticipate and how much they actually experience: in one study of corticosteroid injections, roughly six out of ten patients said the shot was less painful than they had feared, while fewer than two out of ten said it was worse.² That study focused on upper-extremity injections, but the pattern of overestimating injection pain holds across joints.

You might wonder whether getting a numbing shot beforehand (a subcutaneous local anesthetic) helps. The evidence is surprisingly lukewarm. A randomized trial comparing ultrasound-guided hip injections with and without a prior lidocaine injection found no meaningful difference in pain scores between the two groups: patients who skipped the numbing shot averaged about 48.5 out of 100 on a visual analog scale, and those who received it averaged about 39.5, a gap that was not statistically significant.³ A separate study using a similar design confirmed that pre-injection local anesthesia did not meaningfully change the pain patients experienced during the hip injection itself.⁴ The numbing shot itself produced a mild sting (around 20 out of 100), so some practitioners skip it entirely to avoid an extra needle stick that does not seem to help much.

How the Type of Imaging Guidance Changes the Experience

The hip joint is a ball-and-socket surrounded by thick muscles and a dense joint capsule. Getting a needle accurately inside that capsule without imaging guidance is unreliable, which is why virtually all hip injections today are performed under some form of real-time imaging. The two most common options are ultrasound and fluoroscopy (a type of live X-ray), and they feel quite different from the patient’s perspective.

A comparative study found that patients who received ultrasound-guided injections reported a mean pain score of 3 out of 10, while those who received fluoroscopy-guided injections reported a mean of 5.6, a statistically significant difference.⁵ That same study showed ultrasound achieved a successful injection on the first pass in about 98% of cases. Multiple passes with the needle obviously increase discomfort, so higher first-pass accuracy translates directly to a better patient experience.

Ultrasound also has practical advantages that indirectly affect comfort. It does not require a radiology suite, so it can be performed in a regular clinic room where you can be positioned more comfortably. There is no radiation exposure, and the clinician can watch the needle in real time and adjust its path to avoid sensitive structures. Fluoroscopy remains useful for patients whose anatomy is harder to visualize on ultrasound, such as those with very high body mass or significant hardware from prior surgery, but for most people ultrasound is both less painful and more convenient.

The Post-Injection Flare

The procedure itself may last only a few minutes, but the hours and days afterward are where many patients get caught off guard. A phenomenon known as a “post-injection flare” can cause a temporary spike in pain at the injection site, often worse than the baseline pain the patient came in with. This is not a complication; it is a recognized and relatively common reaction.

A prospective study tracking patients after musculoskeletal corticosteroid injections found that about one in five (20.7%) experienced a flare.⁶ The flare typically peaks within 24 to 48 hours and resolves on its own. It is thought to be caused by the crystalline structure of certain steroid preparations irritating the joint lining, triggering a short-lived inflammatory reaction. Not every patient gets one, and it is hard to predict in advance who will.

If you do experience a flare, ice applied to the hip for 15 to 20 minutes at a time can help. Research on cryotherapy for hip procedures found that the hip joint showed the most consistent benefits from icing across pain, swelling, and analgesic use compared to other joints studied.⁷ Over-the-counter pain relievers like acetaminophen are generally fine during this window. Most clinicians advise resting the hip for a day or two after the injection and avoiding strenuous exercise until the flare, if one occurs, settles down.

Why Anxiety Matters More Than You Think

Your psychological state heading into the procedure has a measurable influence on how much pain you report. A study on intra-articular hip injections found low to moderate correlations between the pain patients anticipated and several psychological and experiential factors: general anxiety levels, self-reported fear of pain, whether the patient watched the needle during insertion, the perceived size of the needle, seeing someone else receive an injection, and past injection experiences.⁴ Fear of pain had the strongest relationship with anticipated pain scores, followed by needle visualization.

This means that practical steps to reduce anxiety can genuinely reduce the pain you feel. Looking away from the needle, asking the clinician to talk you through the procedure so nothing catches you by surprise, and using slow breathing techniques are all backed by general pain-management principles. If you have had a bad experience with needles in the past, mentioning it beforehand is worthwhile; some clinics use distraction techniques or allow you to listen to music. The key takeaway is that the fear of the injection often causes more suffering than the injection itself, and the gap between expected and actual pain supports that.

What Gets Injected and Whether It Changes the Pain

Several substances can be injected into the hip, and each has a slightly different pain profile both during and after the procedure.

• Corticosteroids: The most common option for osteoarthritis and inflammatory conditions. The injection itself feels similar regardless of the steroid type, but the post-injection flare described above is most associated with corticosteroids. A placebo-controlled trial confirmed that corticosteroid injections are effective for hip osteoarthritis pain, with benefits lasting up to three months for many patients.⁸
• Hyaluronic acid (HA): A gel-like substance meant to supplement the joint’s natural lubrication. HA injections tend to feel thicker going in because of the viscosity of the fluid. Some patients describe a stretching or pressure sensation in the joint as the gel fills the space.
• Platelet-rich plasma (PRP): Made from your own blood, spun down and concentrated. A meta-analysis comparing PRP with hyaluronic acid for hip osteoarthritis found that PRP showed slightly better pain scores on average at six months, though the difference was modest and was not significant at one to two months or at twelve months.⁹ PRP injections are more likely to cause a post-injection flare than HA because the concentrated platelets trigger a local inflammatory response on purpose, which is the intended mechanism of action.
• Local anesthetic only: Sometimes used purely for diagnosis. A short-acting anesthetic like lidocaine or bupivacaine is injected to see if numbing the hip joint eliminates your pain. If it does, the hip joint is confirmed as the source. This type of injection usually produces the least post-procedure discomfort because the anesthetic is itself a pain reliever.

Diagnostic Injections as a Pain-Source Test

Hip pain can originate from the joint itself, the surrounding muscles and tendons, the lower back, or even the sacroiliac joint. One of the reasons doctors order hip injections is to figure out exactly where the pain is coming from. A local anesthetic injected into the hip joint that wipes out the pain is strong evidence that the joint is the culprit. Research has found that complete relief of hip pain following an ultrasound-guided diagnostic injection of local anesthetic is associated with good surgical outcomes if the patient later goes on to joint replacement.¹⁰

A systematic review of diagnostic hip injections found that pain relief varied by the type of hip pathology. The greatest relief was seen in patients with cartilage damage on the acetabulum (the socket side), where over 93% got meaningful relief, while the least was in patients with cam-type impingement, though even that group saw relief in over 80% of cases.¹¹ Duration of relief from a corticosteroid injection averaged nearly 10 days in that review, while a local anesthetic alone lasted about two days. The short-lived nature of diagnostic injections is expected and by design; their purpose is information, not long-term treatment.

How Long the Relief Lasts

For therapeutic (non-diagnostic) injections, the timeline depends on what was injected. Corticosteroid injections typically begin providing noticeable relief within a few days to a week after the flare subsides, if one occurs. The placebo-controlled trial mentioned earlier found that corticosteroid benefits lasted up to three months in many patients with hip osteoarthritis.⁸ Some patients get longer relief, others shorter. Importantly, the degree of arthritis visible on imaging does not seem to predict how well the injection works: a study that divided patients into four severity categories found significant improvement in hip scores across all four groups six to eight weeks after injection, with no meaningful difference between mild and severe cases.¹² That finding surprises many patients who assume their arthritis is “too far gone” for an injection to help.

Hyaluronic acid injections tend to have a slower onset, sometimes taking several weeks to reach peak effect, but some studies suggest their benefits may persist for six months or longer in responders. PRP follows a similar timeline, with modest improvements over hyaluronic acid at the six-month mark but convergence at one year based on available meta-analytic data.⁹ Neither HA nor PRP is a permanent fix, and most patients who respond well will eventually need a repeat injection or a different intervention.

Risks Worth Knowing About

Hip injections are generally low-risk procedures, but “low risk” is not “no risk,” and the complications that can occur range from trivial to serious.

The most common side effect is the post-injection pain flare already discussed. Beyond that, some patients notice temporary skin flushing or a brief spike in blood sugar levels if they have diabetes, both caused by the corticosteroid entering the bloodstream in small amounts. These effects typically resolve within a day or two.

Infection is the most feared complication. A retrospective analysis of septic arthritis following intra-articular corticosteroid injections found that when infections did occur, they most commonly appeared in two windows: between one and three weeks after the injection, and again between seven and ten weeks.¹³ The overall rate of septic arthritis after hip injections is very low, but any sudden increase in pain, warmth, redness, or fever after an injection warrants urgent medical attention. Do not assume worsening symptoms are just a flare; if there is any doubt, contact your provider.

Another uncommon but serious risk is rapid progressive osteonecrosis of the femoral head, where the bone near the injection site deteriorates. A safety review of intra-articular corticosteroid hip injections reported this complication in about 0.6% of treated hips, appearing two to four months after the injection.¹⁴ This is one reason most clinicians limit the number of corticosteroid injections into the same hip joint, typically to no more than three or four per year, though exact policies vary by practice.

How Hip Injections Compare to Other Joints

If you have had a knee or shoulder injection before, you may be wondering how a hip injection stacks up. The hip joint’s depth means the needle is longer and the approach angle is steeper, which sounds worse but does not necessarily translate to more pain. Most of the discomfort from any joint injection comes from the needle entering the joint capsule and the fluid distending the space inside, and those sensations are comparable across joints.

A pilot study that enrolled patients with osteoarthritis in both hips and knees found that the pain relief from hyaluronic acid injection was slightly greater in the hip group than the knee group, though the difference was not statistically significant.¹⁵ The fact that relief was at least comparable is reassuring: the hip’s deeper anatomy does not seem to make the injection less effective, and procedural pain levels under ultrasound guidance are generally in the same range as knee injections.

Shoulder injections into the subacromial space tend to be rated slightly less painful by patients because the target is more superficial, while injections into the small joints of the hands and feet are often rated as more painful due to the density of nerve endings in those areas. The hip sits somewhere in the middle of the spectrum, and the consensus from the research is that it is more tolerable than most patients anticipate.

Practical Tips for the Day Of

Wear loose, comfortable clothing, ideally shorts or pants with a stretchy waistband. You will need to expose the hip and groin area, and tight jeans are not your friend. Eat a light meal beforehand; there is no need to fast, but going in on an empty stomach can make lightheadedness more likely if you are nervous. Arrive hydrated.

If you tend to feel faint around needles, let the team know in advance so they can position you lying down rather than seated. Bringing headphones and a podcast or playlist is a legitimate distraction strategy, and clinicians generally do not mind. Avoid taking blood-thinning supplements like fish oil or high-dose vitamin E for a few days before the procedure if your provider advises it, though aspirin and prescription blood thinners are usually handled on a case-by-case basis.

Plan for a quiet rest of the day afterward. You can walk and drive immediately in most cases, but vigorous exercise, prolonged standing, and heavy lifting are best avoided for 24 to 48 hours. Have an ice pack ready at home. And if your pain starts climbing sharply after the second or third day rather than improving, that is worth a phone call to your clinic to distinguish a normal flare from something that needs attention.
