Hello, my name is Chris & I\'m a healthy 28yr. old male dealing with what I believe is a Bladder Infection. So this all started off like a month & a half ago. I was peeing a lot, burning when I peed, no discharge, lower back pain, lower abdomen pain & also a itch inside the penis. My family doctor did a urine sample on me & he said the sample came back with a bit of an infection, so he gave me a antibiotic called Bactrim, & said to take it for five days.
