I’ve had trouble as well but instead of being hot, I’m cold. I was always an over- heater but now my thermostat works opposite from everyone else. When everyone is perspiring, I’m shivering. It must be caused by the dysautonomia I was dxd with. Your problem is probably due to same. I wish I could tell you it got better, but it hasn’t. My first bout of Covid was 2/22, then another bout 2/23 and 2/24. I am really sorry you’re experiencing the heat. The cold is much easier to live with, I think. Best to you.
