thanks for your querry...
If there is a post nasal drip
then its a important sign for Chronic rhinosinusitis
. for this take some local steroids
/like Flomist / Furamist nasal sprays if you feel better with this then cont for 4 weeks or if not then take systemic steroids for 1 month in tapering doses like Tab Deflazacort
6 mg 3 times a day for 7 days then 2 times a day for 7 days and 1 time a day for seven day complete this 3 weeks treatment, I think you feel better. thank you. have a nice day
