mine was caused from rush of protiens and sugar leaked from a literal leaking gut . charcot crytaline structures were visable in my bloodstream after a meal upon microscopy. i had to remove the causes and heal the gut . meantime hcl and digestive enzymes may help at mealtime . also no high histame foods no leftovers etc etc . try sealing with demulcients like slippery elm and aloe and marshmellow root a few hours prior to and see if symptoms are the same as a test . ...all soy dairy sugar and gluten were allergens for a while btw.
have you ever been to southwest or treated thoroughly for common american parasites?
