Hi wild_cat

I am new to this group. But have had MG for many years.

My experience with neck weakness/pain has fluctuated over the years.

A few years ago - I tried wearing a neck collar - both a soft one and a hard one for support (and resulting neck pain).

I had problems using both of them. Range of motion was greatly affected and muscle weakness in my neck and shoulders was exacerbated.

But, I still almost always (90% of time) need to have my neck supported. (Sit in chairs with neck support, use neck rests in cars, etc.)

Sometimes my vision changes based on my head position (double vision),

But never have had the feelings/symptoms you describe (fainting, etc). I am not a neuro - but these do not sound like MG symptoms - that I have had or read about. But they do sound serious.

Keep searching for an answer. What kind of doctor(s) have you consulted about these symptoms?
