Thanks for this information, @Learner1 I am not familiar with Theoharides and also the KIT mutation, but might find out something useful here.
Still, my tryptase, histamine and PGD2 are all entirely normal and I don’t have the usual symptom pattern of MCAS. I don’t need or respond positively to antihistamines, don’t have food sensitivities or POTS, etc. All I’ve got is that high Chromogranin A, which could be pointing off in another direction.
I did start the MCAS meds then quickly stopped due to a combination of no benefit and a harmful response to one of them. But I do have ME/CFS in its very low, slow, limiting and unreactive forms, and Dr. K suspects MCAS could be involved, so I want to stay open and learn a bit more.
