I have so many questions, I don't know where to start. And my fibro fog is BAD right now, so I am lucky if I can form a complete sentence! LOL! But I will try. I was having hot flashes all summer long, but then they suddenly stopped. According to my doctor, she said the hot flashes were due to the fibro and not to feminine troubles, which is what I has suspected and asked her to check out. She ran test after test after test, just to be sure. Everything came back "fine" or "normal" or negative" etc., etc. The flashes were horrible. I would wake up at night, drenched in sweat, burning up, and miserable. When those stopped, I was very happy. But since my symptoms have increased and worsened, I have noticed something strange. I am not having hot flashes, no. I am just damn hot all night long. I am normally very sensitive to cold and freezing all year long, so this is definitely out of character for me. Around an hour to two hours before I go to bed, I start heating up. My face is so hot, my husband can actually feel the temperature change. But I won't register a temperature on a thermometer. Soon, my entire body is roasting. I start throwing clothes off, opening windows, and sitting in front of a fan. I will get so overheated, my head will start to pound and I will feel nauseous. And the problem is, it lasts all night long. I wake up feeling the same way. After about 30 to 50 minutes, I will start to feel better and by the time I leave for work, I am my normal temperature again. Yesterday, I had just the opposite thing happened to me at work. I was so cold, I was like ice. My hands and feet literally hurt like I was in freezing temperatures, even though I was inside by my desk heater, trying to warm them up. I was shaking and trembling and a coworker felt me to see if I felt hot on my forehead. She said that even my forehead was like ice. I wasn't able to warm up again until I got home from work. And then, like clockwork, an hour before I went to bed, I was hot. I am rather new to all of this. I was diagnosed with FMS in Augus, female, and I am 30t. Does FMS cause problems with temperature regulation? Or could this be attributed to something else? Any advice, stories, or information would be very gratefully received. Thank you!
