What is geographical tongue?
It is simply a description of the appearance of the surface of the tongue – with areas where bits look kind of ‘bald’ – it might be caused by infection, allergy, injury, spice, hot foods – all kinds of things. It isn’t a serious disease and the tongue will recover without any treatment. Have a look here for more info http://www.nlm.nih.gov/medlineplus/ency/article/001049.htm I would suggest you make sure you have a good diet of ‘fruit and veg’ and maybe you would benefit from some vitamins – particularly vitamin C and the B group of vitamins. Ask your pharmacist for a suitable supplement.
