my husband had radical prostatectomy in 10/07 and seemed to be doing well. 5 to 6 weeks ago he started having excruciating pelvic pain. he has had a cat scan, bone scan, ex-rays and a cystoscope with no results. he is wearing a pain patch, using 800 mg ibuprofen and percocet 10. doctors have no ideas, but he can hardly turn over in bed or even walk. HELP!!!I
