I gave birth 6 month ago ever since I have left buttock pain and legs, also my legs feel weak that I cant even go up the stair. is actually constant and doesn't go away and is getting worst. I cant be to long standing or sitting down. had vaginal delivery with the use of epidural. I gave birth 41 wks. and 5 days I did not dilate or had contraction everything had to be forced. at first I thought it was normal but is just getting worst.
