They took your bladder out? I learned this in my basic Medical Greek and Latin course I think (Cystectomy) I hope you mean a cystoscope look into your bladder. Sounds like a spasm of some sort. You body is talking to you. Please listen and take good notes. Then share with your Dr. The two of you should be able to decide what the problem is or what is the next step to find out.
