To remedy burning sinuses naturally, flush the sinuses out with saline solution and a neti pot, according to Denise Mann for Everyday Health. Irrigate your sinuses daily for preventative purposes and increase the number of times according to the severity of the sinus pain.
Alternatively, inhale steam to alleviate burning sinuses, explains Mann. Add drops of eucalyptus oil or menthol drops to a steaming shower or a hot bath. Ensure the bathroom door is secured to retain as much steam in one area. Inhale the steam deeply for several minutes to loosen up the mucus clogging your sinuses and moisten nasal tissues.
