Sinusitis is persistent nasal congestion, which is heavier in the morning. Sinusitis is also a kind of rhinitis, so the improvement is the same.
Daily advice:
First of all: wash your face with cold water to enhance the ability of nasal mucosa to contact the outside world.
Secondly: If you can, you can breathe more fresh air by running in the morning.
Then: Inhale normal saline into nasal cavity and exhale it repeatedly until there is no dry foreign body in nasal cavity. In fact, this is also a good idea, but it will hurt a little, and I am afraid it won't last long.
Finally: if it doesn't work, use a simpler method: clean the nasal cavity and inject perdane two or three times a day, which will generally improve in about 28 days.
