thanks for your query
History seems that you might be suffering from chronic rhinosinusitis
with some element of labyrinthine pathology.
Take topical steroidal nasal spray
nasal spray, anti inflammatory drug like tab chymoral plus, anti histaminics like levocet.
Take steam inhalation.
Avoid cold and junk foods.
For your labyrinth, take any labyrinthine sedative like cinnarizine
for 4-5 days.
Thanks a lot, take care.
