The nerve may be injured during intramuscular injections into the buttocks. It may also be injured by prolonged sitting or lying with pressure on the buttocks. It may be damaged by pressure from lesions such as a tumor , abscess , or bleeding in the pelvis. In many cases, no cause can be identified. A ruptured lumbar disk may cause symptoms that simulate the symptoms of sciatic nerve dysfunction.
Prevention varies depending on the cause of the nerve damage.
Avoid prolonged sitting or lying with pressure on the buttocks. Reflexes may be abnormal, with weak or absent ankle-jerk reflex. They may include various blood tests, X-rays, scans, or other tests and procedures. Treatment is aimed at maximizing mobility and independence. The cause should be identified and treated as appropriate.
