Hello, Im a 32 year old male about 6'4" and I have been losing alot of weight recently from working out about 4 times a week and running 3 times a week, all for about 8 months now. Ive lost a total of 50 lbs so far and for about 2 weeks now been noticing my nipples are sore and a little red only after my workouts when i get in the shower. Ive heard it may be my test levels or estrogen, please help
