I don't know if this is the correct place to post this but I am a 14 year old male, Indian, following a vegetarian diet (not eating egg but drinking milk and other stuff), I have suffered from knee pains for a long while now a few years at the least they do not constantly hurt but I am constantly aware of the feeling in my knees it feels as though they are very fragile and loose in the socket and when I crouch down my knees crack (It does not hurt but its annoying, worrying and my knees feel good once I have cracked them like that I also have problems with my ankles shins wrists and elbows (the elbows being at the bottom of the list. My wrists feel like they will break when I give them a little squeeze I study Tae Kwon Do I am pretty flexible also I am pretty built I am broad, tall, fit I have big forearms and tiny wrists big upper arms, pecks etc, but my joints worry me. My wrists hurt when I punch something or put a little pressure on them they are one of the weakest of my joints along with my ankles and (I know they aren't joints but shins) My ankles and shins work together to hurt me they hurt after everything, I come home from school they hurt I go for a walk and come back they hurt after exercise they KILL e.g. after tae kwon do, running, P.E a little bit of sport (even playing basketball for 10 minutes) Also my back I have had problems with this for a long time but the doctor and the x ray machine assures me there is nothing wrong with my (lower) back after going shopping it hurts after sports it hurts sometimes after sitting a lil weirdly it hurts and I can crack it extremely loud by turning to my left and right after I have clicked it it feels heavenly along with my knees. Everything except my ankles feels good after I have stretched em off a bit. WHAT THE HELL SHOULD I DO ABOUT ALL THIS?
