I have had ME/Fybromyalgia for about 14 years but recently I have started getting new symptoms. 1. Headaches (was sent for CT scan which was clear). 2. Sore joints. 3. Mouth ulcers and then yesterday twice out of the blue I got an electric shock feeling down my arm. I looked on the net and this can be a sign of seizures, MS or heart problem. I am so scared. I really need your help.
