someone who tells you that they refuse to see you again because of your symptoms and rate of progression is not very professional, i dont care how qualified and thorough they are. its not in the patients best interest and well being to be ditched because the doctor lets it be known they are disturbed by how sick they are. A calm, rational discussion about limits to their knowledge and ability in a certain area of neurology and the need for you to be seen by someone who is knowledgable and competant with that area would be much more productive and professional.
