Between my pecs there is a bone sticking out which is causing the pec muscles to be deformed. when standing straight my left pecl is lower and deformed then my right pec. Ive also been told i have fallen collar bones so my shoulders and neck are always sore and drooping forward. So i was wondering if all this is because all the surrounding muscles are just weak and thats why things are shifting out of place like muscles imbalances. Or do i have something else?
