I am having a sharp pain under my left shoulder blade any sudden movement, cough, or when I press on the back of my neck sends a sharp pain. When I lay down about the only relief I get is to lay on that shoulder. Is is possible just a tight muscle or is it going to be pinched nerve?
You didn’t say how long it’s been bothering you; if it has been less than 2-3 weeks I would recommend conservative care consisting of rest, heat, and anti-inflammatory meds (Advil, Aleve, etc.). If it doesn’t improve in 4-6 weeks you probably need an evaluation to see if there is a neck problem.
