First of all, I don’t know if you’re a male or female, but it sounds like hot flashes to me. It could also be your Thyroid, as your Thyroid controls a lot of things in your body. Have a Thyroid Panel run, you could be either hypothyroid or hyperthyroid and need medication to control it. I take Synthroid to control my Hashimoto’s and Hypothyroidism. Have your general practitioner order a blood panel. Good luck!
