I have terrible sinus pressure. None of the medicine seems to be working. Any good ways to relive it?

I just read someone elses question about sinus pressure and she seemed to be experiencing the same thing. Even sore neck, which made me to believe it was tension headache. Any more ideas?
I don’t have a stuffy nose or anythigng that would seem to accompany sinus. It’s just the headache. I’ve tried the sinus rinse before and it hasn’t done anything. There are 3 differnet Doctors who have allt old me it’s Sinus, that it’s just trapped up there…so I’m going to try the tea thing. I tried the hot compress on my face and head but it didn’t work
