Does ME/CFS affect facial expressions and voice with negative consequences on social function?

Facial expressions play a role in communicating our emotions to other people, and voice is also important.

Do you think that your ME/CFS affects facial expressions and voice?
If so, do you think that this has negative consequences on social function?

This occurs to varying degrees in muscular disorders. Here's a video of a lady with a muscular dystrophy that affects the facial muscles.

To answer my own question, I think this occurs in my illness but in a fluctuating pattern. Fatigue and what I believe is brain hypoperfusion will affect the facial muscles and voice. And also thinking and ability to communicate effectively. I've had to learn to say something when this happens to let others know and avoid misunderstandings.
