Can geographic tongue come and go? i had geographic tongue about a year ago. it healed in a few weeks, but then i had similar spots again two months ago. they went away in just a few days. now theyre back again. is it just flare-ups of geographic tongue,

Geographic : Geographic tongue (benign migratory glossitis) can come and go. It is harmless and has histopathologic characteristics of psoriasis. Perhaps a visit to a dermatologist for definitive diagnosis and treatment options would be helpful. I hope that helps.
