prostatitis
"Prescibed Bactrim for prostatitis. Was showing good improvement after 5 days.  Day 9, big full body hives develop and had to stop.  Dr. thought I was allergic to the sulfa component of bactrim so he prescibed Trimethoprim(the other component in Bactrim) by itself a week later. After 1 pill the hives start again... Was switched to Cipro with slight improvement and then to Doxycycline which is significantly helping after 4 weeks. Going to continue it as long as I'm improving . 70% better now."
