Ever since i was young ive noticed that my left shoulder was different than my right.My left would contract and stick up but my right wouldnt and i can feel my left shoulder blade move but not my right.Its like i have nerve damage or something.It wasnt a big deal until i started lifting and my whole left side of my body seems to be taking off and leaving my right side behind.Is this something that i can work though or should i see a doctor.please if anybody else has had this proublem please post and let me know what you had to do to get the weaker side caught up.i swear its like i have a dead muscle in my back.thanks
