I have been taking .5mg of propecia every other day as recommended by my doctor because I had side effects on the regular dose. Everything was fine until today. It has been 2 months and the side effects just hit me. My head really hurts, my semen is very watery, my testicles hurt, and it's hard to get an erection. It is possible the side effects will go away if I continue using it? What should I do?
