I have an undiagnosed neurological condition, and am very anxious to find some kind of explanation as to what may be happening to me.
Once or twice a year, I go through the same set of symptoms in the same order: 1. blood rushes uncontrollably to the extremities, especially the head which becomes intensely red, 2. heart beats violently, 3. feeling of being extremely disoriented, as if somebody had given me a strong psychoactive drug, 4. loss of perhaps 90% of the strength in my muscles, I can't walk but at best crawl on all fours, 5. loss of control over bowels, violent involuntary evacuation, 6. loss of control over stomach contents, vomiting, 7. blood drains from head, I pass out and remain unconscious for several minutes, 8. I gradually wake up when paramedics arrive and administer oxygen, 9. for the next 3-7 days I am extremely sensitive to stimuli and feel withdrawn.
I have seen a dozen specialists in fields such as neurology and cardiology, who tell me that they have never encountered any patient with a similar condition. I've had a battery of tests taken at the hospital: blood tests, EEG, MRI scan of the brain, EKG, ultrasound scan of heart and of neck arteries, and according to these tests I am in perfect health. The doctors rule out epilepsy, stroke, transient ischemic attacks; the violence of the symptoms makes "trivial" factors such as low blood pressure or low blood sugar extremely unlikely. The doctors tell me that they have no clue what is wrong with me, and that I will probably just have to live with this condition.
I would feel immensely relieved even just to find out that such a condition is known from the medical literature, has a name and a prognosis!
