I had a laporascopic hysterectomy in 2008. The doctor stitched the top of my vagina to my bladder causing them to have to open me up and repair the bladder. Ten days later, I was back at the hospital for yet another surgery due to an active bleeder in my bladder with a clot the size of a small tomato. Since then, I have had bladder spasms, which feel like menstrual cramping. I will have the pain/spasms after urinating, especially at night when I am at rest. I have been on Vesicare for these spasms since 2008 and it seems to work very well. But, the side effects are severe constipation and urinary retention. My doctor has suggested that I do the Interstim Therapy. I went through the trial period and during this time, I did not have any paid/spasms and was not taking my Vesicare. In the past, I would automatically start spasming two days after not taking my Vesicare. The urinary retention also seemed to get better. The constipation was no longer an issue either. 36 hours after having the trial device removed, I began having the horrible pain/spasms. So, I began my Vesicare therapy and am dealing with horrible constipation yet again. But, I am terrified to get the Interstim Therapy. I have read so many bad testimonies and believe me, if something bad can happen, it will happen to me. I had had several surgeries in my lifetime and am only 36 years old. So, do I continue with the Vesicare and deal with the side effects or do I try the Interstim Therapy???? Please help!
