Groin pain is the most common way hip arthritis makes itself known. The hip joint sits deep in the pelvis, and the nerves that serve it run directly through the groin, so deteriorating cartilage inside the joint often registers as a deep ache in the front of the hip, the inner thigh, or both. That pain can even travel below the knee along the same nerve pathway. The good news: a combination of targeted exercise, simple daily adjustments, and the right pain relief strategy can significantly reduce how much that groin pain affects your life.
Why Hip Arthritis Hurts in the Groin
The hip is a ball-and-socket joint buried under layers of muscle. When cartilage wears down, inflamed tissue irritates branches of the femoral nerve and the obturator nerve, both of which pass through the groin on their way down the leg. This is why a problem inside the joint feels like it’s happening in your groin, inner thigh, or even the front of your knee. Pain referred below the knee typically follows the saphenous nerve, a branch of the femoral nerve. Understanding this connection matters because treatments that reduce inflammation or pressure inside the hip joint will ease the groin pain, even though the groin itself isn’t damaged.
Exercises That Take Pressure Off the Hip
Physical therapy is one of the most consistently recommended treatments for hip arthritis. The 2024 American Academy of Orthopaedic Surgeons (AAOS) clinical practice guideline gives it a moderate recommendation based on moderate-quality evidence. The principle is straightforward: stronger muscles around the hip absorb more of the load that would otherwise grind through the joint. A few key exercises form the foundation of most hip conditioning programs.
Stretches (Daily)
A knee-to-chest stretch loosens the muscles around the back and side of the hip. Lie on your back, bend one knee, and gently pull your shin toward your chest. Hold for 30 seconds, rest 30 seconds, and repeat four times on each side. A seated rotation stretch targets the piriformis, a deep hip muscle that often tightens around an arthritic joint. Sit with both legs straight, cross one leg over the other, and rotate your trunk toward the bent knee. Hold 30 seconds, repeat four times per side. You can also stretch the outer hip by standing next to a wall, crossing the leg closest to the wall behind the other, and leaning your hip toward the wall until you feel a pull along the outside of your hip.
Strengthening (Two to Three Days Per Week)
Hip abduction strengthens the gluteus medius, the muscle on the outside of your hip that stabilizes the pelvis when you walk. Lie on your side with the affected hip on top, keep your leg straight, and slowly lift it toward the ceiling. Start with a weight that allows 8 repetitions and build to 12 before adding a pound. This exercise directly reduces the sideways forces that cause pain during walking. Internal hip rotation, done lying on your side on a bench or bed with a pillow between your thighs, strengthens the medial hamstrings and improves rotational control of the joint.
If any exercise sharpens your groin pain rather than producing a mild stretch or muscle fatigue, back off. A physical therapist can modify movements for your specific level of joint damage.
Over-the-Counter Pain Relief
Oral anti-inflammatory medications are the first-line drug treatment for hip osteoarthritis, per both AAOS and American College of Rheumatology guidelines. Ibuprofen and naproxen reduce both pain and the joint inflammation driving it. Acetaminophen is considered a second-line option because it controls pain but does nothing for inflammation, and evidence suggests it’s less effective as a long-term solo treatment for most people.
Topical options can help when you want to avoid the stomach and cardiovascular risks of oral anti-inflammatories. Diclofenac gel (sold as Voltaren) is an anti-inflammatory you rub directly over the joint. Because the hip sits so deep, topical gels may be less effective here than on a knee or hand, but many people still find partial relief. Capsaicin cream, applied as a thin layer three to five times daily, works differently: it gradually depletes the nerve endings’ ability to send pain signals. It takes consistent use over a week or two before you notice meaningful results.
Heat, Ice, and When to Use Each
For a chronic condition like hip osteoarthritis, heat generally works best. It loosens tight muscles around the hip, increases blood flow, and improves flexibility before you move. A heating pad or warm towel applied to the groin and front of the hip for 15 to 20 minutes before exercise or first thing in the morning can make a noticeable difference in stiffness. After activity, or during a flare-up with noticeable swelling, cold therapy helps. An ice pack wrapped in a towel and applied for 15 to 20 minutes numbs the area and reduces inflammation. Some people find alternating between the two gives the best results.
How to Walk With Less Pain
A cane is one of the simplest tools for cutting groin pain during walking, but it only works if you use it correctly. Hold the cane in the hand opposite your painful hip. This feels counterintuitive, but the physics matter: the cane pushes your trunk toward the stance leg and creates a counterforce that reduces the load your hip abductor muscles have to generate. That directly lowers the compressive force inside the joint. For proper fit, the handle should sit at the level of the bony prominence on the outside of your hip, and your elbow should bend about 25 to 30 degrees when you grip it.
Sleeping With Hip Arthritis
Nighttime groin pain from hip arthritis is common enough that it’s one of the signs doctors use to gauge severity. How you position yourself in bed makes a real difference. If you sleep on your side, lie on the hip that doesn’t hurt and place one or two pillows between your knees. Adding a small pillow under the curve of your waist keeps your spine aligned and prevents the top hip from rolling forward, which compresses the joint.
If you sleep on your back, place a pillow or rolled blanket under your knees to slightly flex the hips, and consider a second thin pillow under the small of your back. This position takes tension off the front of the hip capsule, which is exactly where groin pain originates. Stomach sleeping puts the hip into extension and internal rotation, a combination that tends to aggravate an arthritic joint. If you can’t avoid it, a thin pillow under your pelvis helps reduce the strain.
Injections for Stubborn Pain
When conservative measures aren’t enough, a corticosteroid injection into the hip joint can provide significant relief. The steroid reduces inflammation directly at the source. Ultrasound-guided injections have a 100% accuracy rate for reaching the joint space, compared to about 72% for injections placed using anatomical landmarks alone, so it’s worth asking whether your provider uses imaging guidance.
The duration of relief varies. More soluble steroid formulations wear off faster, while less soluble ones last longer, but individual results are unpredictable. Repeated injections should be spaced out, and if you’re considering hip replacement surgery down the line, most surgeons want at least three months between your last injection and the procedure to reduce infection risk. Hyaluronic acid injections are another option, though major guidelines are more cautious about recommending them. Some studies show benefit for moderate arthritis, but results are inconsistent.
Weight and Joint Load
Every pound of body weight translates to multiple pounds of force on your hip joint during walking. The hip bears roughly three to six times your body weight with each step, depending on speed and terrain. Losing even a modest amount of weight, 10 to 15 pounds, meaningfully reduces the cumulative stress on the joint over the course of a day. For people who are overweight, this is one of the most impactful long-term strategies for managing groin pain, because it addresses the mechanical cause rather than masking symptoms.
When Conservative Care Isn’t Enough
Most people can manage hip arthritis groin pain for years with the strategies above. But the disease is progressive, and there’s a point where the joint damage outpaces what exercise, medication, and lifestyle changes can handle. The signs that it may be time to discuss hip replacement include pain that prevents restful sleep despite positioning changes, difficulty with basic tasks like putting on shoes or climbing stairs, and an inability to participate in activities that matter to you. Hip replacement reliably eliminates the groin pain because it removes the damaged surfaces causing it. Most people return to full activity within three to six months after surgery.
