How To Treat Sharp Pain In Upper Pectoral Muscle Due To A Injury?

I tripped and fell on the footboard of my sleigh bed a week ago. Landed above my left breast. My upper pectorial muscle hurt very much, then about 3 days ago I began having a sharp pain in what I believe is my teres minor, right behind the injury site. It feels like I have had a steak driven through my chest out my upper back, on the inside of my shoulder blade. It hurts to cough or sneeze. I cant lift things from above. I am worried I did real damage. I have been switching between heat and ice. Will it go away with time?
