My right upper back hurts when I take a deep breath. It feels like its under the shoulder blade a bit the the left. I dont know if its from 3 1/2 months ago I fell off my horse and broke my hip and maybe did something to my back? i dont know, but it feels like a pulled muscle. I am 13, so I do not smoke. Its worse when I wake up, I take a deep breath and and I have to stop because it hurts.
