Body heat, like hot flashes

Does anyone else have sensations daily, several times a day, of being too warm and even hot, as if you are having a hot flash? I also had an anxious, prickly feeling, until my neurologist prescribed pregabalin. I have had this for 2.5 years. It started within two weeks after I had Covid. Every test I have had showed results within a normal range. My body temperature is always below 98.6- around 97.5. It has always been 98.6. It is as if I don't have a thermostat- I get cold, put on a jacket, and within minutes I get too hot. I have not worn a sweater since this began. Oddly, I don't notice it when I am outdoors. After going to several specialists, I take Lyrica and Veozah, which have helped. My doctor at the Vanderbilt COVID clinic in Nashville has recommended taking spore probiotics and magnesium threonate, vitamin D, 30 min. of sunshine a day, and no dairy products, especially ice cream. Hard cheese, in very small amounts, is permitted. I am never comfortable. This feeling is always with me, just in different degrees.
