Hi There, My friend, 22 yr old female has h/o bilateral ptosis and leg weakness since 1 week. she also had fever sometimes. As per her all labs are normal. she consulted orthopedics and ophthalmologist. and she has been told that it is because of dry i eye but i am not satisfied with that and i ask her to make an appointment with neurologist today. I want to know differential for this condition, can you please help me..?
