At first I suspect it might be a hemorrhoid, but when it didn't go away after a week I'm not so sure anymore. Preperation H does not seem to help the itching or soreness very much, and it's pretty sore and red from the top to the bottom of my buttocks and even a little bit beyond. Every time I use the toilet it irritates it more.
I think it's worth mentioning that I did take antibiotics a few weeks ago for a urinary tract infection. I noticed itching immediately when I starting taking the medication, but it only became severe after I finished taking them.
Is there anything worth trying before I give up and have to be diagnosed by a doctor? If it is yeast, is there anything I can do to kill it?
