Psoas Muscle Pain: Where It Hurts and What Helps

Psoas muscle pain is a deep ache that many people feel in the groin, at the front of the hip, or in the low back. The psoas is a long muscle that runs from your lower spine, along the back of the belly and through the pelvis, to the top of the thigh bone. It helps lift the knee when you walk or climb stairs. Because it sits so deep, pain from it is hard to pin down. This guide covers where psoas pain is usually felt, what tends to stir it up, what may help, and when the pain is a sign to see a doctor.

Where psoas muscle pain is felt

You cannot press on the psoas from the outside, so the clues come from where the ache shows up. People most often describe:

• A deep ache in the groin, on one side or both.
• A pull at the front of the hip, especially when standing up after sitting.
• A band of ache across the low back, sometimes on one side only.
• Pain that travels to the front of the thigh.

The ache often feels worse when you lift the knee, climb stairs, or stand tall after a long time sitting. Many people notice it eases a little when they lie on their back with the knees bent.

A plain warning: the psoas is hard to pin down

Here is the part to take seriously. The psoas lies close to the hip joint, the nerves of the leg, the bowel, the kidney and the appendix. Pain in that area can come from any of them. A hernia, a hip joint problem, a kidney stone or appendicitis can all be mistaken for a sore muscle.

Back pain shows the same difficulty. About 90 percent of low back pain cases have no single specific cause that can be identified (WHO, 2023). If experts struggle to name the source, you cannot expect to name it by feel. So treat "it must be my psoas" as a guess, not a fact.

What tends to stir up psoas muscle pain

Most often it is one of three things:

• Long sitting. The hip stays bent for hours, and the muscle rests in a shortened position. Standing up can bring a pull in the groin.
• A sudden jump in activity. A new running plan, lots of sit ups or leg raises, or kicking sports can load the muscle faster than it can adapt.
• Guarding. When the back or hip is sore, we tense around it. The psoas may join in and stay tight long after the first scare.

If tightness is your main complaint rather than pain, our guide on what causes a tight psoas muscle goes deeper. If the ache sits right in the front crease of the hip, read about iliopsoas bursitis, a different cause of groin pain.

What may help psoas muscle pain

Start with subtraction. Break up long sitting often. Build up exercise in small steps. Walk gently, since easy movement usually suits an irritated hip better than staying still. Warmth in the evening is often welcome.

Hard pulling into the sore groin is not the goal. An irritated muscle tends to answer force with more guarding. What many people find more useful is slow, comfortable movement in which they notice what the hips, pelvis and back are doing. A good place to begin is our somatic exercises for beginners lesson. Our Feldypedia article on hip stiffness and limited mobility explains how the hips and trunk share the work.

How the Feldenkrais Method® approaches a sore hip

A Feldenkrais® lesson does not treat a muscle. We make a movement small and slow, so you can sense which parts are working hardest. Then other parts are invited to share the job. In my teaching, a hip that aches often belongs to a person who has learned to brace their belly and back when they walk or stand. Lying down, we explore small rolls of the pelvis and slow bends of the knee, and notice what else takes part. At Feldy the lessons are spoken aloud, so you can follow them with your eyes closed. This is Feldenkrais® as learning, and it sits alongside medical care.

When to see a doctor

Please get checked promptly for any of these:

• Pain with fever or chills.
• Sudden, severe pain in the belly or groin.
• Pain after a fall or a hard knock.
• Numbness or weakness in the leg, or trouble controlling the bladder or bowel.
• A bulge in the groin that grows when you cough.
• Blood in the urine, or pain with nausea and vomiting.

These can point to hernia, appendix, kidney or hip joint trouble, not a sore muscle. Call emergency services or go to the emergency department straight away for sudden, severe belly or groin pain, a groin bulge that turns painful and will not go back in, or new trouble controlling the bladder or bowel. An ache that has not eased after a few weeks deserves a visit too.

Find where to start

Several movement methods suit a sore, guarded hip, and each goes about it differently. A quick quiz can spare you a lot of trial and error.

Common Questions about psoas muscle pain (FAQ)

What is the best way to ease psoas muscle pain at home?

Start by changing what stirs it: break up long sitting, and build activity up in small steps. Gentle walking and slow, comfortable hip movements usually suit an irritated hip better than rest in one position. Many people find warmth in the evening soothing. If the ache is not easing after a couple of weeks, or you are unsure what it is, ask a clinician to look.

What should I avoid when the psoas muscle hurts?

Avoid forcing a hard pull into the sore groin, since an irritated muscle tends to answer force with more guarding. Avoid long stretches of sitting with no break, and sudden big jumps in running, kicking or leg raising. Avoid pushing through sharp pain. And do not assume the psoas is the cause if the pain is severe, sudden or comes with fever: get that checked first.

Is it safe to move when I have psoas muscle pain?

For a mild, familiar ache that eases with movement, small comfortable movement is generally reasonable. It is not safe to wait it out if the pain began with a fall, is sudden and severe, comes with fever, or brings numbness or weakness in the leg. Those need a doctor first. Movement sits alongside medical care, never in place of it.

How often should I practise gentle hip movement for psoas muscle pain?

Short and frequent beats long and rare. Aim for a minute or two of slow, easy hip movement several times a day, plus short breaks from sitting. Add a longer guided lesson on a few days each week if you enjoy it.

How long does psoas muscle pain usually last?

A strained muscle often settles over a few weeks once the trigger changes, though it can take longer if the load keeps coming. Pain that lingers past a few weeks, keeps returning, or is getting worse is a reason to see a clinician instead of waiting longer. Time frames vary a lot between people.

How is psoas pain different from hip joint pain or a hernia?

They can feel alike. Psoas pain tends to be a deep ache at the front of the hip that changes with sitting, standing up or lifting the knee. Hip joint pain is often felt in the groin too, with stiffness and pain on turning the leg. A hernia usually shows as a bulge that grows when you cough or strain. Only an examination can tell them apart.

When should I see a doctor about pain in my groin or hip?

See someone promptly for pain with fever, sudden severe pain in the belly or groin, pain after a fall, numbness or weakness in the leg, a bulge in the groin, or pain with blood in the urine. Appendix, kidney, hernia and hip joint problems can all look like psoas pain. Sudden severe pain, or new bladder or bowel trouble, needs the emergency department straight away. Also book a visit if an ache simply refuses to ease after a few weeks.
