My sister and I have been sick for 3 (me) and 4 (her) years and have not gotten a diagnosis. We are having symptoms from several different systems (neuro, gastro, cardio, etc.) and don't know what to do. We have seen neurologists (I have seizures; my sister doesn't), an internist, an endocrinologist and several family doctors, and they all tell us to go somewhere like the Mayo, but they are widely varied in their opinion of what kind of specialist we should see. We have no insurance, but we can pay cash up to a point. We just can't keep going to different kinds of doctors without some kind of clue as to what we're doing. ANY SUGGESTIONS?
