Sinusitis
Infection in the sinus cavities, of which we have four in our skulls. The largest of the sinuses is the maxillary sinus, located just above the roots of the upper molars. A pressure cousing infection in this area can be mistaken for tooth pain. Maxillary sinusitis is sometimes characterised by pain in the jaw or face that changes when you lean over, lay down, or stand up. It can literally cause pain with every footstep.
