Does anyone else get hot hands/face after minor exertion?

tldr; hands are 5 degrees hotter (at the warmest part) after standing and folding clothes or doing stretches and simple exercise. At physical therapy, I have to stop after nearly every exercise to put my hands on an ice pack to cool down.

I have a diagnosis of mitochondrial myopathy and my immunologist says that overheating is normal, but I haven't come across anything in my research that shows something similar to my experience. My husband has a thermal camera, so I know that at rest, the palm of my hand is 92.5 F and my fingers at the tips are 69.8 F. After maybe 5 minutes of doing normal everyday stuff around the house, my hands and face feel more and more hot, and I feel like I'm going to faint. My face is flushed a little but not enough that my husband notices unless he's looking for it, and I don't sweat, and my hands get a little red but again, not something that's really obvious. I've got a bunch of other symptoms but I'm really just looking to see if anyone else has the hot hands/face problem, and how they deal with it.
