My 83 year old father has bladder cancer. Last year, he had a tumor "shaved" but the cancer has spread to the bladder wall. He is not in good enough health to have his bladder removed. He has COPD. He has a catheter thru the uretha and has undergone radiation therapy to try to shrink the tumor. He just finished radiation therapy about 3 weeks ago. His bladder spasms are more frequent, with a lot of burning. We were hoping to get the tumor shrunk enough so he could have a SP catheter.NOTHING seems to relieve the painful spasms. He has tried several pain medication, but nothing is working. Does anybody have any suggestion to help with the painful spasms? Thanks for all your help
