15721 Psoas Syndrome

Overview

Psoas syndrome is a condition where the psoas muscle — a deep muscle in your lower back that connects your spine to your thigh — becomes tight, irritated, or strained. This can cause pain in the lower back, hip, or groin, and may make everyday movements like standing upright or walking feel difficult.

Psoas syndrome is not as common as ordinary low back pain, but it is a known cause of persistent hip or back discomfort, especially in active people.

It can affect anyone, but it is more often seen in people who do a lot of running, dancing, cycling, or sitting for long hours at a desk. It can also appear in older adults who have muscle stiffness or changes in posture.

Symptoms

Common symptoms

• Dull ache in the lower back on one side
• Pain in the front of the hip or groin
• Stiffness when getting up from a chair or out of a car
• Pain that worsens when you lie down, bend backwards, or stretch the hip
• A feeling of tightness in the deep hip or lower belly area

Symptoms in children

• Complaining of a sore back or hip
• Limping or favoring one leg
• Trouble sitting still in class or during car rides
• Pain when bending forward to tie shoes

Symptoms in older adults

• Hip pain that is mistaken for arthritis
• Difficulty standing up straight from a seated position
• Aching in the groin or lower back that limits walking distance
• Muscle stiffness in the morning

Causes

Main causes

• Overuse of the psoas muscle from repetitive activities like running, cycling, or sit-ups
• Prolonged sitting, which keeps the muscle in a shortened position
• Sudden increase in exercise intensity or duration
• Muscle imbalance between the strong psoas and weaker abdominal or buttock muscles
• Leg length difference, which can strain the muscle over time

Risk factors

• Playing sports that require frequent hip flexion, such as dance, gymnastics, or soccer
• Working at a desk for many hours without proper posture breaks
• Being pregnant, which changes posture and puts strain on the deep core muscles
• Having had hip or lower back surgery

When to see a doctor

See a doctor urgently if:

• If you have sudden back or hip pain with weakness or numbness in a leg
• If you lose control of your bladder or bowels
• If you have a fever with back pain, or redness and swelling around the hip

Book a routine appointment if:

• If back, hip, or groin pain lasts longer than two weeks
• If pain interferes with work, sleep, or everyday activities
• If you have had repeated episodes of hip stiffness or aching

Diagnosis

Your doctor will listen to your story, ask about your activities and posture, and do a physical exam. They may press on the psoas muscle area or ask you to lift your knee toward your chest to see if that reproduces your pain.

Tests that may be done

• No single test is needed to diagnose psoas syndrome
• Imaging such as ultrasound or MRI may be used to rule out other problems like hip joint issues or a disc problem
• Your doctor may suggest a movement assessment to see which muscles are weak or tight

What to expect at your appointment

Your doctor will likely spend time asking about your daily routine, exercise habits, and any recent injuries. You may not need any scans at first. A clear diagnosis often comes from the physical exam and how your pain responds to simple stretches or rest.

Treatment

Treatment for psoas syndrome focuses on releasing muscle tension, restoring good posture, and gradually building strength in the core and hip muscles. Most people improve with non-surgical care.

Self-care at home

• Apply a warm compress or heat pack to the tight area for 10–15 minutes to relax the muscle
• Use a supportive chair that keeps your hips slightly higher than your knees
• Take regular breaks from sitting — stand up and gently stretch every 30 minutes
• Try gentle hip-flexor stretches, like kneeling and pressing your hips forward, as long as they do not increase pain
• Avoid activities that cause sharp pain, but keep moving gently to prevent stiffness

Medical treatments

Your doctor may recommend physical therapy, which can include manual therapy, guided stretching, and strengthening exercises. In some situations, a health professional may use treatments like dry needling or shockwave therapy. Anti-inflammatory pain relief may be mentioned by your doctor or pharmacist, but never start any medicine without checking with a healthcare provider first.

When is surgery considered?

Surgery is very rarely needed for psoas syndrome. It is only considered when conservative treatment has been tried for many months and symptoms are still severe, and even then only after a specialist evaluation.

Living with this condition

Living with psoas syndrome means being kind to your body. You may need to modify how you sit, stand, and move for a while. Many people find they can keep doing light activities like walking or swimming, but they avoid sudden twisting or heavy lifting until the muscle settles.

Lifestyle tips

• Adjust your workstation so your hips are at a comfortable angle
• Alternate sitting and standing throughout the day
• Sleep on your side with a pillow between your knees to keep your hips aligned
• Wear comfortable, supportive shoes to reduce strain on your back and hips

Diet and exercise

A balanced diet with plenty of protein, fruits, vegetables, and water helps keep muscles healthy. Gentle exercises like walking, swimming, or stationary cycling can maintain fitness while you recover. Strengthening your core and glute muscles gradually will help support the psoas in the long run.

Mental health and emotional wellbeing

Living with chronic pain can be frustrating and worrying. You may feel anxious about returning to exercise or worried that the pain will never go away. It is normal to feel this way, and speaking openly with your doctor or a trusted friend can help. If you feel low or hopeless, talking to a mental health professional is a sign of strength, not weakness.

Prevention

Yes, to a large degree. Keeping your psoas muscle flexible and your core strong can help prevent this condition. Simple habits like stretching daily, avoiding hours of uninterrupted sitting, and building up exercise intensity gradually all make a big difference.

Complications

If left untreated

• Chronic lower back or hip pain that persists for months
• Tightness that leads to poor posture and further muscle strain
• Difficulty walking or performing daily tasks
• Increased risk of developing hip joint irritation over time

Long-term outlook

The outlook for psoas syndrome is very good. With proper care — especially physical therapy and lifestyle adjustments — most people recover fully and return to their normal activities. The key is to be patient and consistent with your rehabilitation.
