title: Myasthenia gravis as a cause of facial pain.
abstract: A case of myasthenia gravis is described. The diagnosis was confirmed electromyographically and immunologically; the presenting features were those of myofascial pain. Attention is drawn to the association of myofascial pain with other systemic diseases and stresses the need to look critically at the patient for evidence of a systemic origin for myofascial pain.
