There is something called Familial Ptosis that tends to be asymmetrical in presentation.

A TIA can also cause unilateral ptosis. There are many causes. A person can also have MG and other causes for ptosis at the same time! What sets MG ptosis apart is that it is fatigable and causes binocular double vision.

I've known people who have had Bell's palsy and MG. Have you seen a neuro-ophthalmologist?

How long have you been on steroids?

The caution here is that someone can have more than one disease state at a time.
