My dear friend has had this for about a year. She is at her wits end with it. Almost constantly she has a really sore, painful mouth including her lips, inside and out. She also gets pins and needles pains in her lips and her mouth is really dry. She has been to the Dr, all test have come back clear. She has tried thrush medication, anti biotics, changing her toothpaste. The only relief she gets is from sucking on an ice. Has anyone else had this? If so have you any advice..she would be so grateful!
