Sphenoid: This sinus is the most posterior of the sinuses. Sinusitis here occurs after the other sinuses mainly. Symptoms will still include headache and people complain about it at the top of the head or in the back of the head. It is quite nonspecific as it is more rare. Diagnosis can be by sinus xr. If in doubt, go see your doctor for proper diagnosis please.
