The main work of your hip flexors is to bring your knee toward your chest and to bend at the waist. Symptoms associated with a hip flexor strain can range from mild to severe and can impact your mobility. If you don’t rest and seek treatment, your hip flexor strain symptoms could get worse. But there are many at-home activities and remedies that can help reduce hip flexor strain symptoms.
Disc degeneration remains a key cause of chronic low back pain and the pain often persists despite surgery. NIH-funded basic science and preclinical studies are investigating molecular-level mechanisms that cause discs in the spine to degenerate, as well as protective mechanisms involved in disc remodeling that may diminish with advancing age. Such studies may help identify future therapeutic strategies to block degenerative mechanisms or promote remodeling processes. NIH also is funding early research on stem cell approaches to promote disc regeneration and rejuvenate cells of the nucleus pulposus, the jelly-like substance in the center of intervertebral discs that loses water content as people age.
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.
