I have had all the thyroid panels. I’m slightly hypothyroid, which doesn’t really fit with the heat. I don’t have nor have never had high blood sugar. I believe it is some underlying condition causing dysautonomia. But nobody has any good ideas what that might be. The more frustrating aspect is I haven’t felt like any specialist I’ve seen is particularly interested in doing the digging required to answer this. I have zero quality of life at this point and I don’t see any help with this on the horizon. My daughter deserves a mom.
