I'm already dealing with this problem for quiet long and did some research on it..google brought me here a few times so I decided to make an account, hoping you could help me out.
I'm an 18 year old guy who plays football (soccer like some people say) and I love sports in common. I try to run a few times a week + I have football training and match at sundays. About 3 years ago I decided to start doing some very little """workout""" at home to get stronger, to compete with the big guys in football (I was a little shorter than the other ones, not anymore now). I was a little young and didn't really think about what I was doing and I think that now I'm paying the price for that.
I did push-ups mainly, as far as you could call them push ups, I don't really remember. The only thing I know is that the orientation in right arm was the best, because I'm right-handed. I don't need to explain to you guys that because of this, right arm (+chest?) took the most weight and maybe got more developped. In the beginning I didn't know it would happen and didn't notice because I never really looked in the mirror.
But when I turned 16 I started noticing a spot on left chest, which was diagnosed as becker's naevus (doctors weren't sure about this). (For those who don't know what it is: it's a brown spot, caused by too much pigment in the skin which stays there forever. You'll see when I post picture.) To get back to the story: this spot is a very embarrasing thing for me, and since then I started to look in the mirror more and more, being unsure about myself. I don't remember when I noticed the inbalance of chest muscles but I did, and it made me even more unsure about body. Now I had ugly muscles AND a brown spot, world kinda collapsed.
Until now I've managed to hide chest for other people, but I'm so sick of hiding and I want to be like anyone else,although that's impossible for me. I hate it when people say "you're a beautiful guy", because I KNOW I'm not with that spot. So, to get a little more confidence about own body, I'd like to get a nice muscled chest.
So I'm begging you guys to help me find the problem, and put me on the right track and give me tips on training. I DON'T go to a gym, but I have dumbbells,a barbell, a bench, and some resistance bands at home to work with.
PLEASE help me

ps: on which site do i have to upload a picture so I can get it here? thanks
