I fractured my back in 2013 in 3 places due to a fall on the ice, however I have now been told my largest shoulder muscle on left arm has been torn almost all the way thru, the pain is out of control and I was given a cortisone shot a month ago but the condition has got worse, I have fevers a lot ,vomiting , diarrhea and numbness with severe pain and now constant loss of feeling in my limb, which is spreading down my left side, I simply cannot continue like this anymore, my doctor is of no help, what can I do?
