Peety - what antibiotic did your doc put you on? Right now I am applying bactroban twice a day and Sunday I am going to start Bactrim. I am waiting to starting Bactrim because I have to work all weekend and I don't know how it is going to effect me. I too think I have had MRSA for a while because I had a cut on my leg that I got in June that took all summer to heal and now it is still red and weird looking. It doesn't look inflamed or infected, but it scarred in a really weird way.
Please, please, please take this seriously. I won't go into extreme detail about my mom's situation, but she worked in a nursing home and contracted MRSA from one of the patients there that was infected. Hers was in her sinus passages and was told for months she had a chronic sinus infection. I will spare you the scary details about her struggle, but it can take control, especially with someone who already has their immune system working extra time from UC.
I have seen the Bactrim prescribed to those who have skin MRSA. If it does not completely heal it, make sure your doctor knows! Have them culture it again. If MRSA is still present, it can "reactivate" itself.
Please let us know how you do with this. Good luck-----sometimes it seems like it's always something, doesn't it?
