I ve had brain surgery and back surgery.Plus, both arms tingle in the early morning along with leg sensation and have A/FIB.

Tingling of arms, and legs.  You had surgery on brain, and back.  I advise you to consult a neurologist for diagnosis and treatment.  I usually prescribe to my patient with such symptoms neurotrophic injections for 10 consecutive days, and then periodically, calcium supplements, and painkillers.  Avoid taking potato, other tubers, tomato,egg, chicken, and and seafoods.  Wishing for a quick and complete recovery. Thank you. </s>
