I need a home remedy for a bad sinus headache!?

I can’t get to the store today, and I have a bad sinus pain headache. Is there a home remedy I could try? I don’t have eucalyptus oil (someone had told me to try boiling it and breathing the steam but I don’t have any). I keep putting a warm towel on my face and it feels good, but as soon as I stop the pain is there again. Help! This is so uncomfortable.
