I've had this horrible severe pain in my upper right arm, wrist and right side of my neck for the last 4-5 weeks. it feels very heavy and a times feel like shooting pain and/or chills kind of sensation on the right side of my head. I also feel as though some times my hearing is distort or get that hard sharp pitch when everything is so quiet?; when I feel like that I get sudden panic attack or anxiety. my ears also get extremely hot and read. My right hand gets very cold and purple and heavy. These symptoms have been going on and off for the last 4-5 with the exception of the sharp pain in my arm which is very constant and at times I am even unable to sleep because of it. Please help me understand what is wrong with me and what should it do. it is affecting concentration at my job and interfering with the enjoyment of my personal life.
