I dont know what i am allergic to but i get this very frequently and repeatedly. It develops gradually, first there is sneezing and throat irritation like something is stuck in and cant be swallowed or spit out. Within a day or two this gets worse and i develop breathing problems. Ultimately i have to see my doctor, he prescribes me some anti allergic drugs like Montelukast and fexofenadine with antibiotics and cough syrups. I am fed up taking so many pills and precautions for unknown reason, please guide me so that i can get a proper treatment.
