Same question as before-is my body normal? read description.. FYI I'm just curious and a wee bit concerned.?

sorry(my iPod isn't very good). let's see,it hurts when I eat,I have spots in 'certain' places,and my stomach is rather tight yet I have stretch marks,my legs seems to be very 'large',vains stick out all over my body,I can dislocate my knee's,my ribs don't seem to show even though my stomach is skinnier than anyother part of my body.
