You are having lingering effects of a respiratory tract
infection which is causing your symptoms. Shortness of breath
is because airways become hyper sensitive after a bout of infection and go into spasm with littelest provocation. You should continue with either nebulization with asthalin
or take a inhaler like aerocort 3 to 4 times a day. You may also take a montair lc, some cough syrup and a pain killer. Take rest and soon you should be alright.
