What is your thinking on this?
myasthenia gravis?
I think that’s what you mean.
The coughing jags, and the vision. The prism glasses. The dizzy spells. The concussion, or whatever happened, and she was rushed home. I am not clear about what really happened. I am suspicious. I am not a doctor. Not making a diagnosis. Have a family member, and a dentist, who have it.
I thought of another reason I suspect possibility of myasthenia gravis- her weight gain. Typically treat with mega doses of steroids, which cause weight gain. That, along with the gagging coughing fits and the on/off of the prism glasses. But, who knows.
