Hello, Welcome to HCM, as you are having allergic manifestations for last two years, I would suggest you to test your blood for absolute eosinophill count (AEC), this is one of the important indicator of presence of allergic reactions in the body. I would suggest you to undergo skin prick test for most prevalent allergens in your surroundings like dust, pollen, mite, food and chemicals. This test help us to identify the allergen causing all these symptoms and you can avoid those allergens, if it not possible to avoid the allergens you can go for immunotherapy. For the present symptoms I would advise to take tab levocast, meanwhile consult your doctor to get information regarding skin prick test. Thank you.
