My hands get so HOT it's insane. I also get needle pinch sensation (but not all the time). I got an MRI of my brain last Oct and they found a small mass that could indicate MS, but that was "ruled" out when no lesions were found in the Spinal cord. The pain...well it’s weird, hard to explain, it comes up to my forearm and lingers there for a few days. I really stopped paying attention but this time, it’s been there for almost 6 days. I drunk water, just in case I had too much sodium and was dehydrated (like I read on some forum) but that didn’t take care of the problem. Not sure if it’s relevant but this doesn’t happen on both hands at a time, usually my right arm. I was also tested for carpal tunnel and was negative. Basically, I want to make sure I am NOT loosing it. Please help me.
