I am a 56 year old woman. About 4 months ago I fell into a door frame, the pain was extreme. The pain has gradually got worse, I have pins and needles and numbness from my hand to the top of my shoulder, it's only on my right arm. The pain is worse just below the top of my shoulder, I can still do things but the pain is just there all the time, it's affecting how I'm sleeping too. Sometimes I feel like I can hear the bones cracking and grinding inside. I think the pain is related to the fall, but I went to my doctor who said it was an infection. There was a little bruise afterwards and no swelling.
What could this be?
