My adult son has had a peppery taste in the back of his mouth...as if he had put a spoon of black pepper in his mouth. He no longer enjoys eating because of this. Years ago he was diagnosed with HS disease, could this have anything to do with it or is this something we should worry about.
Howell come to ChatDoctorAt the most chances of dermatitis need to be ruled out if this is not like that then this could be functional condition and not due to any disease, dermatitis can be treated with local mouth gargle and Provide iodine gargle would be best, else this is nothing to worry, take care and have a nice day.
