I am a 21 year old male and have never been really hairy. Just recently i have noticed that hair has started growing on my upper arms, my shoulders, a lot more on my back, starting to grow on the inside of my bicep and inside of my forearm. I know guys get more as they get older but i just feel like the hair is growing in places that i shouldnt get hair and i feel like i get hairyer everyday. Is this normal or can there be something causing this? I have had my harmone levels checked a little while ago and im not taking steriods or testosterone although i have taken testosterone in the past (like 5 months ago) but never expierenced increased hair growth. Or could it be like a tumor on a gland or something like that?
