With that sort of description- my inclination is to think more in terms of SEIZURE disorder rather than stroke. Biting the inside of the cheek or the tongue UNKNOWINGLY by patients happens during seizure episodes, not typically during strokes. However, if the patient has already HAD a stroke and does not have good control of chewing or mouth movements then, it is possible to accidentally bite on the cheeks from the inside. Very frustrating for patients to say the least. If this information has been useful to you would you consider providing me a STAR RATING? Thank you.
