I'm also a worry wart, and I worry about having fibromyalgia
Everything started about 1.5 years ago. August of 2014. After doing a lot of exercise and running, out of nowhere, I noticed one night, that when having intercourse with my wife, my erections would sometimes HURT. It was bizarre. I just thought maybe I strained something, and thought nothing of it.
Then after about 2 weeks of erectile pain, I went to the Dr., and he was not concerned and said to give it time.
