......PN board but has anyone been plagued by Geographic Tongue otherwise called Benign Migratory Glossitis?

Again one of those terms like idiopathic....'benign' seems to demean everything that you are feeling. However to get to the point, why at every point in my life when I've been in the lead-up to a major illness like Adrenal Insuffciency, Ascending Cholangitis, Asthma, Pneumonia and now PN that the Benign Migratory Glossitis has been and is at it's worst????

If it's that 'benign' why does it rear it's head, as a kind of prophet of impending ill health?? Any insights, flippant or otherwise would be appreciated!
