For 1.5 years I've been experiencing pain on my left side...neck, then shoulder, then wrist, and now elbow and shoulder. Family Dr. tells me I probably have arthritis and tennis elbow. I am not athletic and can't think of what I might have done to cause this. However, shortly before all this started, I did get really sick with vomiting and diahhrea for over a week. I suspected food poison. Then, three months later when the peanut butter recall was announced, I went to the cupboard to find a nearly empty jar with the recall numbers stamped on it. Could there be a connection? Why left side only? Anybody have a cure for tennis elbow if that is truly what I have now? Ice...heat or both? Please help. Miserable
