Hi Dr, a friend of mine has an abscess in her tooth. She has had a high fever, reaching as high as 103.3. Shes been tired all day long, coughing alot, vomiting, dry heaving and now she thinks she may be hallucinating a bit. She has not seen a dentist or dr. I plan on bringing her to ER later tonight. My question is, can the abscess get bad enough to cause hallucinations? My email is: YYYY@YYYY
