You have to continue the nasal spray- Flomist during the monsoon season two puffs twice a day. Remember to take the spray with your head leaning forward.
Continue Pan 40mg for another 7 days in empty stomach and do Dispirin gargles( 1 tablet Dispirin in 1/2 glass water) twice a day for 7 days
Also get a CT PNS done so that the extent of your sinus disease can be found out.
