I was wondering if I could have mast cell activation syndrome -mastocytosis came back negative. I have had severe allergies all my life, but I was never tested to see what I was allergic to. 16 months ago I became very sick when our 4th cat came to live with us. My ige was 253-normal is less than 114. I am allergic to 10 things, and cats were off the chart. My symptoms are facial flushing, itchy skin, dizziness, tachycardia, stomach pain with diarrhea, headache, muscle cramps, and chest pain and tightness when exposed to animal dander. And smells bother me also that never did before. I had to get my own apartment. Any help please
Please do a skin prick allergy test to cat dander and if avoidance is impossible, you can try immunotherapy
