I wake up couple times a night with my legs on fire an my hair soaking wet from being to hot. It can be freezing in my bedroom but I'm feel hot inside my legs are cold externally sometimes while hot internally. This happens everynight! I will tell briefly what is wrong with me. I have peripheral neuropathy in both hands an legs an feet, i have arthritis, osteoprosis, Gastroparesis, I've survived cancer 3 times, i have lots of disc issues in my back im on oxicodone 6x a day, vitamin calicium and D, trazadone for sleep an panic attacks that these on fire sensations cause me to feel like im having. I've had over 36 surgeries since birth due to gastro problems. I've had a hysterectomy but no hormone replacements i have a piece of ovary that is still producing. That basically covers it. Hope some one might be able to give me some advice.
