I m having pains around my left shoulder. Not on top of my shoulder, but on my back and around my ribcage. It hurts to move my left arm or perform simple activities. It hurts when I laugh, sneeze, or cough. Even when I m walking, I cannot stand up straight or I wince in pain. Only on my left shoulder though. It started around last week when I was working. I thought nothing of it because the pains were minor, but today it started to really hurt. I had my mother rub some Icy Hot on the area that hurts but it doesn t help relieve the pain. What can I do?
