Temporomandibular joint disorder, or TMJ syndrome, is an acute or chronic inflammation of the temporomandibular joint, which connects the lower jaw to the skull. The disorder and resultant dysfunction can result in significant pain and impairment.
If you know you have TMJ have you had your joints looked at with an MRI and cone beam Ct scan? Have you ever had myofacial massage to see if that helps with your sinus pain?
