bacterial infection
"If it wasn't for having to stay out of the sun while taking, I'd give it a 10.  I was given this for something besides my ears at the time, but I clearly remember that it suddenly and quickly cleared up a long standing issue with my ears being slightly sore for quite a long time.  My doctor at the time told me to remember that.  I seem to have the ear issue again and am thinking of asking my current pcp for at least a short time treatment with this."
