Thanks I have had some blood tests and everything was normal apart from female hormones. They have tested me again today so waiting for results. I dont have a temperature and i spoke today to a person knowledgeable on encephalitis who seemed to think my condition would deteroriate much more quickly than mine if i had it. It should show on tests anyway. I am worried the extractions and dental cleanings have released lyme disease...i have no idea if it could do that it was just something someone suggested. I have CFS/ME ...20 yrs, never knew i had lyme, dont know why it would suddently come out now unless it was hiding in my peridontal pockets. Never ever hallucinations/intrusive disturbing images in all my life before. I feel like I have something in my brain, its always fogged, confused, cant think straight or clear. I took your advice and got myself checked ...asked doctor if i could see neurologist but he has recommended a psychiatrist ...oh no...i never had any of this before the dental work...
