Symptom narrative

Within days, started having allergic reactions to foods and skincare that had never caused reactions before in 42 years. Burning in my face, swelling in my face, hives over my arms, neck and chest. Went to emergency room for second reaction, not stopped by Benedryl. Symptoms match Mast Cell Activation Syndrome. I now have allergic reactions to stress and certain foods (although allergy tests show no allergy to foods). Controlled mostly with diet, the doctors I have seen don?t know anything about MCAS, so no treatment so far.
