I have no idea what to do next. I’ve been feeling off and on horrible since February when I thought I had the flu. Never quite recovered. Super fatigued. Ten days ago I had the first episode of extreme heat. I NEVER get hot, I’m someone who always runs cool. Since then, I’ve had a couple of episodes a day where I suddenly get super hot, light headed, etc. then it passes and I get cold. Any ideas? I had a Lyme test done and it was negative. The only other major symptom, besides the fatigue, is lots of postnasal dripping, no stuffy nose, just drainage down my throat. I also had a crazy vertigo episode three weeks ago. I’m starting to get very tired of this and don’t want to get anxious on top of everything!! Thanks
