Hi, may I answer your health queries right now ? I have a vaginal polyp that I've had for several years. Two weeks ago I was given 5 days of Bactrim for a bad UTI (with blood in my urine) at a Walgreen's clinic. (It was on Saturday and my Physician doesn't have saturday hours). I went to my physician yesterday because I began experiencing frequent urination. The urinalysis dip-stick just showed some protein and a small amount of something else; not enough to explain the frequent urination. I was given Bactrim yesterday, waiting for the urine culture results. BUT, my polyp is painful now when I sit! Could this polyp be infected? I have chills, and feel like I have a low grade fever. Please advise. Thank you.
