The answer is Mast Cell Activation Syndrome! The life long genetic version, not the post Corona virus version but it's generally the same.
Basically I'm allergic to... Everything? Myself? Something I could eat yesterday? I can itch all over for no reason, I get a consistent mystery rash with no exact cause, I have low blood pressure, brain fog, joint problems, digestive problems, no energy, spent quite some time with dumping syndrome...
Generally it's like I have an auto immune disorder but I'm missing the key components that say it's Lupis or something else. Actually, at least three generations of the female side of the family have had some sort of mast cell problem but only a handful of the symptoms have been treated if we didn't have "white lady hypochondriac" diagnoses. Yeah, guess who doesn't like going to the doctor unless they need to. My appointment is next year :/
So, if you have had a life long battle with general allergic to something symptoms that aren't going away or had Corona virus and have lingering allergy of any kind symptoms talk to a health care provider about a Mast Cell issue.
