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.
