I am scheduled for a Thymectomy on the 5th of December at Walter Reed Army Hospital. Does anyone have any advise??? Or things I should before and after the procedure. Background: I first diagnosed with generalized MG in 2000 and was able to control it with meds and when into remission for several years. Over the past three years my out breaks increased in frequency. Well after returning home from my last deployment my MG became uncontrollable with medication and finally I decided on the thymectomy.
