Diffuse Muscle Weakness

Conditions that cause weakness of facial muscles include myasthenia gravis, Bell's palsy, and amyotrophic lateral sclerosis (ALS, also called Lou Gehrig's Disease), among other conditions. See your doctor and describe as precisely as you can the facial muscle symptoms you are having.

Just one more question:

Has your weakness been something you've noticed all your life? For example, were you able to keep up with the other kids on the playground? Have you had trouble getting up from a squatting position ever since you were a child?

Yes, I've had weakness problems all my life.

No, those are not problems I've had.
