This may not seem like a fibro issue but I read the low core temp is a common fibro symptom. I took my temps for two weeks many times during the day. It was never 98.6F. The average was about 96.8. That doesn't bother me too much unless it's the root cause of a chronic immune system weakness. The really annoying thing is my skin temp gets very high very often. It's a chronic problem.
Although untested with a skin thermometer because I have not found one, it is often almost hot to touch. I have to use cooling pads all the time, sitting on them while I work and having one under my head while I sleep.
I rarely can sleep through the entire night. When I wake up I feel too hot. The side I slept on is especially hot, and sometimes it takes half an hour to cool down enough to get back to sleep. Sometimes I just can't get back to sleep. This causes chronic fatigue and ruins the entire day.
What on earth could be causing the simultaneous combination of low core temperature and high skin temperature?!
I am guessing there is some kind of vasoconstriction, but why? The heat always seems trapped and can't dissipate or circulate. I never had this problem when I was a kid. In the last year it's got worse. Now my stomach, legs, and feet heat up and they didn't a year ago.
Blood pressure, heart rate, etc., are all normal. Nothing showed up in testing to explain the mystery.
I've noticed lately that I have a problem with chronic hyperventilation. The breathing rate when I wake up can get as high as 120 breaths/minute (two/second). That is 10x normal. Hyperventilation is known to cause vasoconstriction, but what could be causing the hyperventilation in the first place?
Something in my autonomic nervous system seems haywire. Anybody heard of low core temperature and high skin temperature? I Googled it and found something on injection molding!
P.S. Hyperventilation, I read, causes excess salivation. This is a chronic problem, too.
