Symptoms of MG usually improve when more relaxation is given to the muscles. The first signs of MG include problems in the eyes such as:
Drooping of one or both the eyelids.
Diplopia (double vision), this can be horizontal or vertical, or both. This defect resolves if one eye is closed.
The speech may sound soft and nasal.
The person may choke easily, which makes it difficult for him to eat, drink, or take any pills. When the person drinks, liquid may come out of the nose.
The person may face difficulty in chewing food, particularly something hard, such as steak.
The smile and other facial expressions may be lost, if the muscles that control facial expressions are affected.
MG can cause weakness in the person’s neck, arms and legs, but this usually happens along with muscle weakness in other parts of your body, such as the eyes, face, or throat
