What works for me is to take 5mg of diazepam and 2 Benadryl and sit in a recliner with a pillow under my knees. It will not feel better at all at first. Within an hour you should see a difference. This is what I do for bladder spams. If you have a muscle relax, try taking that. My bladder spasms get so bad that they make my bowel spasm. I feel as if I need to use the bathroom really bad. Is that what you are feeling?
