On two of those days I took 2 pills, i.e. 1g, taken at once. Two days after starting the
Biaxin I was prescribed doxycycline, 2g total taken over the course of 7 days.
On day 8 after swimming I noticed what looked like a skin fold on the end of my penis next to the urethral opening (about 1/8 inch). Unsure whether this was something normal for my penis or not, I have been observing it since. It is not an open sore or a blister, it is not red, and it is painless.
