Thank you Annie, we have had a wonderful summer and still seem to be having it.

Yes I have read of the relationship between geographic tongue and celiac disease, for which I haven't been tested but have no other symptoms that would indicate it. I am familiar with it as one of my sons is so affected.

I agree with you that one should not substitute the internet for the doctor and will discuss these issues with him when next we meet (I keep adding things to my list!)

Thank you for your concern and advice, it is much appreciated.

Cheers, Marian
