Menopause causes the hot flashes, but the face tingling is definately a calcium
imbalance, could be low, could be high....this also causes many other symptoms of pain and anxiety, nervous system, heart, bones, muscles, just about every system in the body runs on calcium, if that is out of whack, it makes you hurt really bad with many symptoms.
Look at hypercalciema and hypocalcemia, also look at the cause, thyroid and parathyroid glands.
