Yesterday I was putting things away in the fridge and stood up quickly and the freezer door was open...I slammed my upper Left back/ shoulder into it HARD. A few hours later I have had extreme pain, burning, tingling in my left arm . These symptoms have lasted, getting increasingly worse for 24 hours with no relief. I ve done ice, heat,tried to reposition for comfort to no avail. Any suggestions on what to do or if it will just get better in time?
