Dizziness. This is not normally associated with tm disorders. This is more likely related to inner-ear disorders and you should consult an ent.Ear.
Dizziness is tricky. Dizziness associated with a tmj/tmd ailment can occur, but is not necessarily a common symptom. I get referrals from ent's quite often, and the equilibrium (balance) may be compromised by a TMJ element. But you should definitely have an ENT examine you first prior to considering TMJ as the main cause.
