shoulder pain, it's like between two bones. it hurts when I breathe in, big breath=big pain as if something stings me. not muscular.

allo, I am the person in question. When I fill my lungs with air it hurts my shoulder like I'm pinching a nerve and it hurts so much that it cuts off my breathing like when I have asthma attacks. When I empty my lungs too, it makes a sharp pain. It's really in the shoulder it doesn't feel like a muscle pain it feels like a pressure point.

I didn't get hit. It started during the night while sleeping, I would wake up because it hurt and no I don't have pain in my back
