Sam,

Kendra's advice is wise--it's good to be on the look-out for new symptoms. But there's also hope that you may never have them. 15% of people with MG only have ocular symptoms. See http://www.myasthenia.org/docs/MGFA_Brochure_Ocular.pdf (a brochure from the Myasthenia Gravis Foundation of America).
