would a discectomy help with lumbar (SI) pain? I have a herniated disc L3-L4, impingment on the L4 nerve root , and a L4-L5 herniation; impingment on the L5 nerve root. MD says right disectomy since most of my pain is on the right. Right buttocks , right hip (burn/ache) right top thigh burn, ache, sometimes stabbing. Calms down for a while then goes severe for months. Due to auto injury.
