Epidural injections of steroid drugs are frequently used to treat sciatica, despite limited evidence for their effectiveness. Moreover, these treatments are based on the assumption that reducing local inflammation in the vertebral column will relieve pain, but an association between structural abnormalities, inflammation, and sciatica symptoms has not been clearly demonstrated. NINDS-funded researchers are using a new imaging technique that can detect inflammation to better understand what causes chronic sciatica pain and to provide evidence to inform treatment selection.
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.
