I woke up a week ago, and the cord that runs on the right side of my neck really ached, went down along my collar bone, and into the joint of my right shoulder. Now, it's in the front and back part of my neck on the right side and around my lung area as well. Would this be considered a pinched nerve or pulled muscle? I've had numbness in my right arm for the last year or so. When it's not numb, it aches like hek in my elbow and shoulder. But it's never gone into my neck. It's worse when I lay down, or try getting up. Then subsides after I'm up for a few hours (on asprin). Will heat or cold applications help this? I'm about to make an appointment with a doc, or chiropractor, but what is best to do for this in the meantime?
