I Have Interstitial Cystitis And A Urologist Injected Rimso And

I have interstitial cystitis and a urologist injected rimso and I had to hold it for a painful 2 hours and go home and then pee it out and now my stomach is pouched out and am hurting so badly! Hard to pee at all. It is the Sunday after I had this done on this past Friday morning. I look a few months pregnant and am really hurting. What do I do now? Do you know?
