I have a sister, 52 years old, who was hospitalized recently. She has slurred speech, tingling and dumbness in the hands and feet, difficulty controlling her movements, difficulty walking and difficulty controlling her bladder. She has a past history of the following autoimmune diseases: Guillain Barre & myasthenia Gravis. Is it possible for those to flare up again? What other issues might we be looking at. A spinal was done yesterday and we are waiting for the results.
