Hello. Three days ago I had a bout of what I believe was food poisoning, as five others who attended the same event as me got severe nausea two days later. I recovered almost completely within 24 hours but ever since I have had a weird intracranial pressure-type sensation that turns painful when I move my head up from a lower point (stand upright after bending down, stand up from a seated position etc.) I have been drinking LOTS water and electrolyte drinks and dont feel dehydrated. Is this a normal symptom or should I go to a doctor? I worry a bit as I did have a brain abscess from an infection many years ago and while I know I am no more likely to get a reoccurrence  than anyone else, the similar pressure sensation makes me nervous! However I dont want to rush off to the doctor if it is a common part of recovery from food poisoning.
