A friend of mine is type 1 diabetic. WOke up with blurred vision, then had partial facial numbness around the right side of head, eye area and mouth. Went to ER, had bloodwork done which showed dehydration, high potassium levels, ct scan was negative for tumors, he has been working out twice per day -hard. Is there a virus perhaps or anything that comes to mind? Which doctor should he see now-an endocrinologist or a neurologist for follow up? Just trying to help him out.
