I had my flu shot one week ago. Pain in left arm. Extreme pain...not at the injection site but about 2" below and to elbow area. Figured I would let my doctor know and I also had Neurontin on hand. I was told to use my 300 mg 3x day. It is not helping. Pain is like ice to the bone. Miserable. Never will have another shot. This is for the birds. No relief from NSAIDS...nothing touches it.
