Sinus

Sinus problems, too, give rise to headaches. The sinuses are small
spaces in the facial bones just below the facial skin. The spaces are
concentrated in the nasal region, temples and around the eyes. Sometimes,
due to infection, these spaces get inflamed with mucus and infected as well.
This leads to the headache that is the result of sinusitis. There are
many causes for sinusitis, which are allergy, a deviated nasal septum, and
severe cold, enlarged parts in side the nose, and acute ongoing infection.
