"Mitochondrial dysfunction is a common cause of peripheral neuropathies."

My mitochondrial dysfunction is getting worse. In the last week my fingers, toes, and nose have all suddenly become cold very often. Room temp. is 24C and they feel the same as they did when the previous week when it was 19C. They don't heat up easily or quickly. RT needs to be 25-26C for fingers, toes, and nose to not feel cold. The problem is at 26C my scalp starts to feel as if it's burning. So there's a very narrow temp. range I can be comfortable at (0.5-1 degree window). Now I'll wake up at night and my feet will be cold. I'll add a thick blanket, but they won't heat up, and I can't get back to sleep. Which just makes my energy lower and mito function worse.

I'm going to load up on mito supplements.
