One side of my labia is inflamed, feverish, and very painful. I am also having trouble emptying my bladder . I went to the doctor 3 days ago and was put on Bactrim. The next day it was worse so I went back and they tried lancing it. But it was not filled with pus, but just swollen. I m supposed to wait a couple more days to see if the antibiotic works, but it is just getting more swollen and painful. There is little to no drainage from the lancing. They also did a urinalysis on the second day, but that was clear. Should I really wait?
