I'm having a shoulder/neck issue for the last few days. I don't know what I did and if perhaps I slept on it wrong or what. Now it is constantly sore on my right shoulder blade and up my neck and now today my right arm is sore. I get this everyone once in a while and someone mentioned it might be lactic acid buildup? I've tried ice, massage, Tylenol and various things which are never a quick fix but I need it to be better by Saturday (preferrably asap). Does anyone have any suggestions I can try? Would a heating pad help? Other than that I'm ready to get 'er done!!
