The trouble occurs during rainy and winter season only. [/INST] Hello, Welcome to Chat Doctor, As you are known allergic to dust, you should be very careful otherwise it may be dangerous to the life. I would suggest you to undergo absolute eosinophil count (AEC) which will be raised in the allergic condition. For the present symptoms you can take Tab Monte LC which helps to control the symptoms, but it is temporary. You need to avoid these dust allergens to protect yourself from getting these allergy symptoms. I would suggest you to undergo skin prick test (SPT) to identify the type of dust causing these symptoms, and you can prevent yourself from exposing to this dust. Otherwise, you can prefer immunotherapy either with subcutaneous immunotherapy (SUIT) or sublingual immunotherapy (SLIT). Thank you. </s>
