I am getting sharp pains in the area of my bladder. They are not in any particular time frame or sequence, just every now and then, I ll be just sitting around or might be doing something and then a sharp pain in that area. I am calling them bladder spasms. I have stopped taking 2 medications that iI recently started, before the pains started, but the pains have not stopped. I m hoping that they will soon as I was taking Flexeril for back pain to help me sleep at night and stopped that about 3 or 4 nights ago, but still having the pains. he other med was my percocet, but I have been taking that for many years on and off for my back and didn t have this problem before. I have had bladder spasms in the past, but I can t remember what I did to stop them.
