Allergy, feeling feverish. For a cure.

From last few months my allergy problems have aggravated. The problems are Continous sneezing, it doesn't stop until I take any histamine, I feel shortness of breath and sore throat all the time, during night I am not able to sleep properly and if taken montelukast I feel drowsy in the day, countinous mucus, slight head ache and tired eyes. I feel feverish. It's certainly not normal cough and cold and this problem has increased since I moved to Bangalore almost an year ago. My recent AeC count is 2096 and Eosinophils is 22.3% which are way above normal range while total wbc count is normal. I had also done prick test for allergy few years ago and I was allergic to certain types of dust mites etc but no food allergy as such. I am frustrated of taking montelukast everyday and looking for a cure. Thanks a lot for any suggestions/recommendations or leads.
