TMD stands for Temporomandibular disorder. It is a condition that affects the jaw joint and the muscles that control jaw movement. TMD can cause pain in the jaw, face, neck, and ears, as well as problems with biting and chewing. Some people also have difficulty opening their mouths or have a clicking or popping sound when they move their jaw. TMD can be caused by a number of things, such as injury to the jaw, grinding or clenching of the teeth, or stress.
A migraine is a type of headache that can cause severe pain, often on one side of the head. It can also cause nausea, vomiting, and sensitivity to light and sound. Some people see flashing lights or blind spots before a migraine, called an "aura". Migraines can last for a few hours or even a few days. They can be caused by different triggers, such as certain foods, stress, changes in weather, or hormonal changes in women. Some people can tell when a migraine is coming on, while others have them without warning.
