Some people (like me) with fibromyalgia also have a condition called temporomandibular joint syndrome (TMJ). This condition causes jaw pain. In my case it’s on the left side of my jaw.
If you have this condition, you’ll notice that your jaw makes snapping or popping noises when you open and close your mouth, especially when eating. You may also have trouble opening your mouth all the way to chew or speak. It makes it difficult to eat and can get quite painful at times. Jaw pain can make it difficult to eat.
Sometimes TMJ also causes headaches and pain around the ears.
Some people get braces to correct this, but it doesn’t always work.
