What should I do?

Okay the last couple of days every time I eat I dry heave and feels like my stomach is sick and I can't feel my bladder and apparently during surgery something happened to my catheter they can't just fall out pretty sure so how could it just fall out I bet they yanked it out accidentally and right above my incision there is a lump on one side and it feels like pins and needles on that spot and it burns to pee they put me on medicine for uti and it's been over a week and it hasn't gotten better.is it just me or does something seem wrong.the doctor acts like it's no big deal.
