Unsure, you are compensating by raising your left brow otherwise your ptsosis on the right side would be even worse.

I do the same. Your facial symptoms are just like mine, raising one eyebrow to compensate the ptsosis, droopy corner mouth on same side as ptsosis. All my facial issue have been attributed to the MG. They wax and wane with all the other MG symptoms. Mestinon make them better temporarily as does rest.

Looks like MG to me!
