Hey treefrog, I recently had an ultrasound done to me. It revealed a 2cm nodule(nod-jew-el) in the left side of my neck. I got a biopsy to follow it up. I take propecia and Im only 19. You think I should tell my doctor about the propecia im using? Do you think that the nodule in my neck could have anything to do with my hairloss? If I fix this problem will my hair grow back? I need my hair and propecia costs alot!!!!
