I have so much pressure in my head and feel like such poo!
The one thing that worked really well with me during my first pregnancy was to take a washcloth and get it as hot as you can stand it. Then I would lay it on my forehead close to the bridge of my nose. It helped to loosen up some of the pressure and relieved my headaches when my nose would get clogged up. You could always try that.
