If it burns you are using too much H2O2. Don't forget to mix with salt and baking soda. The soda will help a lot. I suffered for years and this has cured me. No more pressure in the head which was driving me crazy. and best of all a bottle hardly costs anything. Also don't forget to do the flip and turn sinus rinse. This is the best method to get to the sinusus over the eyes.
