Yes. My 77-year old father is having alternating bouts of hot flashes (he soaks his clothes with sweat) and hard chills. He has extreme neuropathy in both feet and muscle pain in the front of the thigh then the muscles pain switches to the calves. He has almost constant muscle twitching in his calves and uncontrollable bending of his big toe (but not all the time like the twitching). In past 6 weeks has lost 15 pounds, extremely weak (stays in bed mostly), and becomes easily fatigued. He is being treated for diabetes with insulin and had prostate surgery/radiation for cancer five years ago. Thank you for your time.
