TMJD (what I had) might fit:

Many people with fibromyalgia must also face the pain caused by temporomandibular joint disorder, an illness that affects the muscles and joints in the face. TMJ disorder can cause a variety of uncomfortable symptoms, including nausea, headache, dizziness, and jaw difficulties. About 90% of fibromyalgia sufferers are thought to experience facial and jaw pain, and a large number of these probably have TMJ disorder. Diagnosis of TMJD can sometimes be difficult, especially for those who already have fibromyalgia.

What is Temporomandibular Joint Disorder?
TMJD is a disorder that affects the functioning of the temporomandibular joint (TMJ), more commonly referred to as the jawbone. TMJD also attacks the muscles and cartilage throughout the face, head, and neck. TMJ dysfunction can cause a variety of problems, ranging from headaches to a locked jaw, so it is important to get any symptoms of TMJD properly diagnosed.
