When my allergies and sinus back-ups gang up on me I try the hot/cold approach. I get a hand towel and soak it with very hot water and place it over the offending side of my face until it starts to cool. Then I repeat the process with a bag of frozen peas. The cycle usually lasts about
25 minutes with hot/cold compresses in place for 5 - 7 minute intervals. This must do something to the gunk that causes the pressure because at the end of my hot/cold packs I usually get a total 'gush' of gunk flowing out of my head and almost instant pain relief. Worth a try for anyone with this pressure thing and also is great if you have thyroid or high blood pressure and are limited on which decongestants you can use. No prescript
ion needed!
