Trying to find out why my left arm jerks sometimes when I m doing nothing. I do have a LOT of arthritis in the neck, severe, and I also have mini seizures for which I take meds. I never lose consciousness, and only once was anyone but me aware that it happened. Can you read me, or am i supposed to enter this somehow. Oh, am I supposed to pay ? Lol. If so, then I ll get out of here now, and sorry for your time.
