Is your wife on any meds? For example, Xanax or Ativan? It sounds like she is really 'keyed up' and needs something to relax her. I have experienced this 'jumpiness' but nothing shooting through my arms. And yes, I have been what seems like immobility. I am currently taking 37.5mg of Paxil Cr and Ativan as needed. Those meds help me. If your wife is not taking any meds, have her see a doctor.
