chest is concave

my right side of chest is straight and is normal while my left side is inside, i mean like its concave. im too skinny and the shape of my chest can be seen easily. Is it some kind of disorder or disease or only an imbalance of my chest. will it get fixed with doing body exercise or joining a gym?

Hello, you don't say how old you are or how long you have had this for? I think that exercise could help a bit, but your best bet is to go to the doctor and see what they say.

Oh sorry about that. I'm 21 years old. i dont know if my chest is like that from childhood. But i've noticed it like before 4-5 months. Maybe I'll go and see a doctor first
