I am on .25mg finasteride every day. Of course, I read about complications and side effects. I just noticed that my nipple once or twice during the day was itchy or tingly. I can't see any puffiness or gynecomastia starting. Should I stop it? My chest looks the exact same as it did unless I'm failing to observe something. I'm a bit concerned. Of course, this could be all in my head, but it did itch out of the blue. This only lasted 30 seconds or so and has not been persistent.
