The UTI, you were on one of the big gun antibiotics so I would be more concerned about your gut right now..........the idea for the UTI OTC med was good for the burning with urination.........it will turn your urine orange.........I mean really orange.
I would drink as much fluids as you can and try to walk and see if you can pass gas and get rid of some of the bloating.
I agree with calling your physician if you are not feeling better shortly in case you are obstructed. Darvocet may cause constipation. But you have gone to the extreme here very quickly.
Keep posting an dknow we are here for you. Gentle hugs to ya.
