I think that it is because the RSDS is taking over the urithra. I have taken many pain pills in my past due to having Endometriosis, Poly-Cystic-Ovarian syndrom, IBS, Kidney Disease, and Heart Disease. So...I do not think that the pain meds or the psych meds are the cause at all. I have the same problem with the problem peeing, and it only showed up after I was given RSDS.
