impulses produced by the nerves and the responses of the muscles. This test can confirm how severe a nerve root injury is. More Information CT scan MRI X-ray Treatment For pain that doesn't improve with self-care measures, some of the following treatments might help. Medications The types of drugs that might be used to treat sciatica pain include: Anti-inflammatories Corticosteroids Antidepressants Anti-seizure medications Opioids Physical therapy Once the pain improves, a health care provider can design a program to help prevent future injuries. This typically includes exercises to correct posture, strengthen the core and improve range of motion. Steroid injections In some cases, a shot of a corticosteroid medication into the area around the nerve root that's causing pain can help. Often, one injection helps reduce pain. Up to three can be given in one year. Surgery Surgeons can remove the bone spur or the portion of the herniated disk that's pressing on the nerve. But surgery is usually done only when sciatica causes severe weakness, loss of bowel or bladder control, or pain that doesn't improve with other treatments.
