About two months ago I had a flu shot. About two weeks later I got sick and my arm started aching shortly after. I went to my walk-in clinic and was told I had tendonitis and was prescribed ibuprofin. One week passed-no better. I went to my doctor and was sent for an arthrogram-results normal. I went to a third doctor. He said that it was a toxic flu shot. Vicodin for a week. Felt great for the week plus. Now back to the original problem.
I can lift normal, swing my arm forward and backward, but can't lift it out to my side like putting it on my car door or when using an ATM machine. It feels like a knife stabbing me in the arm at about the place where the flu shot was administered. Everbody is stumped.
Can anyone offer suggestions?

Sincerely;
Steve J. Korper
