I have been having ongoing health issues since September. It started with severe chest pains and many tests later they can't find anything. A couple weeks later I started having numbness and pins and needles in my left arm and leg,a week later it went to the right side too. I have blood tests done and everything comes back fine. Now today my right hand is shaking uncontrollably, worse when I hold my arm out and my hand is sideways. What do you think it could be? Thank you. Theresa
