Iliopsoas syndrome, which is also called psoas syndrome or iliopsoas tendonitis, occurs when the iliopsoas muscles are injured. Lower back pain is the most common symptom; however, pain can also occur in the hip, thigh, or leg. The iliopsoas bursa, which is a fluid-filled sac located on the inside of the hip that reduces rubbing and friction, is also likely to become inflamed due to the proximity of the two structures. When this happens, the inflamed bursae will make it difficult to move.
If low back pain gets worse or does not improve after two to three days of home treatment, contact a primary-care physician. The physician can evaluate the patient and perform a neurological exam in the office to determine which nerve root is being irritated, as well as rule out other serious medical conditions. If there are clear signs that the nerve root is being compressed, a physician can prescribe medications to relieve the pain, swelling and irritation; he or she also may recommend limitation of activities. If these treatment options do not provide relief within two weeks, it may be time to consider other diagnostic studies and possibly surgery.
