I hope that this belongs in this section. For about a month now I have been experiencing pain in my left arm. It is when I will lay my arm down wrong or when I am lifting anything. It is from my wrist to the middle of my forearm. To decribe the pain you know when you have a bruise and when someone pushes it it hurts that is the same pain I am having. Does anyone know what this could be?? It is not my whole arm it is the outside of the lower half of my arm.
