since more than one year i m suffering from coughing. daily for three hours cough starts, cant breath, bit wheezing sound comes and throat not clear. little little phlegm goes out. if i spit it out then after three hours cough stops, i can breath properly and there wil be no wheezing sound, i have post nasal dripping, mucus wont come out from nose. nose wil be dry. M taking homeopathy treatment from 6 months... no use. before that i used nasal spray that also no use. once i took Allegra-120 tab every day... then there was no problem at all. i was very well. when i stopped that tablet again this problem started. so what is this ashtma or sinus. pleasr reply doctor.... i cant bear coughing... sometime i feel like m suffocated and going to die
