About 6months back I started sneezing where there is dust. after few months, I began to show mild symptoms of asthma, mainly recurrent cough & breathing problem. Later it subsided. And then on, whenever I come in contact with dust,polluted air, rest I cannot find out, I started coughing, sneezing& experience running nose. It lasts fr a while after I move from there. I always have itchy eyes. Sometimes I face a sore throat. Since 4days, I find myself sneezing & showing all the above symptoms very frequently. Showing the symptoms against slight dust, oil, increased fan speed etc. Should I take any treatment? Or will it gradually go away?is there any remedy?
