I will go to the docs about this, but have been worrying all weekend. I have a sore tongue which is kind of yellowy, and think it is perhaps oral thrush. Been using Corsodyl mouthwash and brushing teeth and tongue a lot, but not going away.
Having looked it up on the internet I have seen it can be a symptom of diabetes and now am terrified. I am slightly overweight (BMI 27.7) and really worried about this. Any mnetters have experience of this?
