I've only dust mites allergy but when i eat pulses, vegetable diary product i get weakness cold feets itchy scalp my all test are normal except ige 498?

Oral allergy syndrom: I am not sure what "pulses, vegetable dairy product" is but i may have an answer for you. Patients who have a dust mite allergy may also have allergies to pollens. People allergic to pollen may have the "oral allergy syndrome" also called the "pollen food allergy syndrome." in essence, if you are allergic to pollen you can react to fruit and vegetables that are similar to the pollen.

food allergy?: Pulses vegetables are from the legume family. I am assuming that a pulses "dairy" product is soy milk. Legumes include beans, soy, peanuts, and peas (chickpeas too). I am not sure about your cold feet, but the itchy scalp could be a food allergy. You did not indicate that you have been tested to food. I would suggest that.
