I have a 28 year old niece who has extreme fatigue (has been in bed for 2 weeks). She has pain which she describes as bumping your elbow and get a jolt of pain and numbness but her whole body is affected. They have ruled out MS, complex migraine and spinal injury. She had an episode that lasted 3 months, was ok for a couple of months and has returned. Do you have an opinion on which way we should be go regarding diagnosis and treatment.
