Facial pain and pressure seen in sinusitis could be caused by many other conditions. Other possible causes of these types of symptoms include:

• Colds that affect the nose (upper respiratory infections).
• Allergies.
• Noncancerous (benign) growths in the nose (nasal polyps).
• Tension, cluster, migraine, or other types of headaches.
• Tooth grinding or temporomandibular (TM) disorder.
• Toothache.
• Cancer in the nasal cavity or sinus (rare).
• A sudden, stabbing pain in the face that occurs at irregular intervals (trigeminal neuralgia or tic douloureux).
