why is my back hurting( both left side and right about midway point from neck down; kidney areas even extending to rib cage) ? i began experiencing this sudden pain friday afternoon
two hours after i had minor surgery on two areas of my back. i had 2 sebaceous cysts removed. one on the middle-right side of my back (like beneath the right shoulder blade), the other on the center of my most lower part of my back--right above the buttocks. when the pain first started, it came suddenly. to me it feels almost as though it is unrelated to the surgery. i mean, why the kidney(s) area? well this pain feels almost like a cramp feels in a leg. however, given the area, it also causes a bit of difficulty breathing as it hurts when my lungs expand. also, it hurts so badly that it limits my movement drastically. this pain came friday and lasted until sunday. by monday, it appeared gone. it came back today after retuning home from work. is this pain related to the surgery? if not, then why the sudden onset after the surgery?
