I Had Two Hard Falls On My Buttock About 2

I had two hard falls on my buttock about 2 years ago and messed my back up. I have had back surgery thinking that would take care of my buttock, but it didn’t after back surgery I have a drop foot. My buttock is still bothering me. I have had all kind of test. One Dr. told me I had a tumor on my buttock, but nothing to worry about. My back Dr. is suggesting I have some rods and bolts taked out thinking it might give me some reliefe. My Buttock bothers me all time! What do you suggest?
