I am tired and have sinus pressure in my head and I need !
Have you tried saline nasal spray?
There is other, more aggressive nasal spray too, but, you are not allowed to use that for longer than a week. Saline nasal spray you can use as long and as often as you like. It comes in various packages. The sprays that almost make a kind of mist when applied are most comfortable, in my experience. But, you can also sniff water with the right amount of salt dissolved in it. Feels very awkward though.
