Rectal Pressure and Muscle Spasms

I have had rectal pain and pressure for the past 7 months.  I have been to both a GI Dr and Colorectal Surgeon for evaluation and tests which include a flex sigmoid scope, pelvic CT scan, rectal and vaginal ultrasounds, proctoscope, and a pelvic MRI.  My CT and rectal ultrasound did show an area of swelling that was against the rectum, but the MRI showed nothing.  It was determined, other than the IBS I have, that I have pelvic muscle spasms.  I have already tried Elavil with no luck--couldn't tolerate the side effects at only 10mg.  Have used Ultram which works temporarily but doesn't solve the problem. My next step is to try Pamelor at 10mg dose.  I have heard of internal massage for those muscles and wondered if anyone has had success with that.  Also, does anyone know of a therapist in the Pittsburgh PA area who is familiar with this problem.
