Ok I am not sure where to post my story, so I am posting it here. I have had a 15 year battle with prostate issues. Burning in the penis, vibration in penis that is almost constant that shoots down my left leg to my ankle.
I am 43, and last April, I had a cystoscopy. Uro told me I had possible interstitial cystitis and also my prostate was enlarged. So he put me on Elmiron and Finateride. I took finsateride exactly 10 months. It seems to have helped my prostate issues, but had occasional flare ups.
The past month or so, my right breast was enlarging. So I called the doctor, (who was on holiday…typical), so another urologist told me to stop taking finasteride, and made an appt. for the 15th of this month. So it has been 7 days now, my breast is not going back to normal, and a day after stopping the drug, the burning in my penis returned and has burned 24 hours a day since stopping finasteride 8 days ago. I am not sure if it is the finasteride doing this, or the heavy pushups I have been doing that is aggravating the penis nerves. This morning, I noticed a slight curve protruding inwards on the shaft of my penis while it was erect. Ejaculation burned like the devil, which is nothing new to me. But I am scared to death after reading this forum and learning about post finatseride side effects. I feel like a time bomb now 
I swim laps at least 4 miles a week, have been doing pushups on my knuckles to build up my pecks and hopefully reduce the fat in my breast. My diet is very limited I cant have any spicy foods, cant have vitamin C, too much to list. I am single (since my sex drive is history and sex is painful, I cant and have no interest in finding a girlfriend)I am 6’3 tall, stay at 203 to 205 lbs, so am not obese.
Anyways, thought I would share this story here. I hope 10 months isn’t long enough to get the bad side effects, but I know am not that lucky. The breast and the recent curving on the penis is what is working me now, along with constant burning.
