See a doctor ASAP: If you have a doctor make an appointment real soon or go to an urgent care or er. The cause may or may not be difficult to discover and treat but the symptoms are dangerous. Before those symptoms cause other problems, get some help. Until then - keep well hydrated - water or sport drinks with balanced electrolytes may be a good idea. Go now, okay?
