 Sinusitis or migraine? Migraines and headaches from sinusitis are easy to confuse because the signs and symptoms of the two types of headaches may overlap. Both migraine and sinusitis headache pain often get worse when you bend forward. Migraine can also be accompanied by various nasal signs and symptoms — including congestion, facial pressure and a clear, watery nasal discharge. These are due to involvement of the autonomic nervous system in a migraine attack. In fact, studies have shown that most people who see a health care provider for sinus headaches are found to have migraines instead. Sinusitis, however, usually isn't associated with nausea or vomiting or aggravated by noise or bright light — all common features of migraines. Sinusitis usually: 
Occurs after a viral upper respiratory infection or cold
Includes thick, discolored nasal mucus
Is associated with a decreased sense of smell
Causes pain in one cheek or upper teeth 
 Headaches due to sinus disease often last days or longer, and migraines most commonly last hours to a day or two.
