Rubbing a 50% solution of DMSO and water to the temples and face over the sinus passages I have found gives relief in 5 minutes for the sinus headache, keep reapplying every 10 minutes until relief comes for more severe headaches. Nettle Tea and Turmeric work well against the pollen allergy. I mix 1 teaspoon of Turmeric in a little milk and add 1/8 teaspoon of black pepper for better absortion and drink 3 to 4 cups of Nettle Tea a day.
