I have a deep sick feeling in my upper arm for nearly 5 weeks now. I CAN NOT sleep at night now and can not find any position of my arm that it doesn t hurt, especially when laying down. Ice makes it feel extreme worse. I m a platelet donor and that isn t going well now. I get this intense pain in my entire arm when I donate platelets and now this feels the same, but it doesn t quit. I think this all got started 5 weekends ago shoveling gravel for 3 hrs. Right Arm. I can t use my right arm when driving, brushing my teeth and using this keyboard makes me weak/light headed.
