It can result in double vision, drooping eyelids, trouble talking, and trouble walking. Onset can be sudden.* The initial, main symptom in MG is painless weakness of specific muscles, not fatigue.* The muscle weakness becomes progressively worse during periods of physical activity, and improves after periods of rest. Typically, the weakness and fatigue are worse towards the end of the day.* MG generally starts with ocular (eye) weakness; it might then progress to a more severe generalized form, characterized by weakness in the extremities or while performing basic life functions* Those affected often have a large thymus gland or develop a thymoma.
