I too developed deep cracks in my tongue mid treatment, also associated with thrush and mucositis. I had an extremely sore mouth which made eating very difficult. But after treamant it is a gradual process of healing. So tell him to hang on in there it does get better. I have just been to check my tongue and yes there are still some deep fissures. I don't think they were necessarily the cause of the pain, it was all the other things going on. Sally
