A couple weeks ago I started getting extreme pain in my lower stomach area. I almost passed out, twice and I could barley move. After visiting the Er & numerous docs.. all they found was a 3mm palp on my gallbladder. From my urine they found that my while blood cells were high, and decided to put me on a 10 day levofloxin antibiotic. My stomach pains went away after a few days.. i am now off of the antibiotics and my pain is mostly mild now, however i'm getting UTI symptoms like having to urinate often, burning sensation and soreness. My doc tested me for cultural yesterday and my urine came back clean.. im wondering what this can possibly be, maybe a side effect from the antibiotic. I haven't had an STD exam for about a year and i'm wondered it can even be that.. am i tripping?
