Glossitis/Tongue Inflammation and Fissures

I have developed deep cracks in my tongue and am now unable to eat any spicy foods or carbonated dinks. I don't know why this occurred but would love to find a solution can you advise me.

Cracks, or fissures, in the tongue may result from dental problems, eating hot spicy foods, alcohol, smoking or anaemia. Herbs that help are:
* sage, taken as a tea and used as a mouthwash 4 to 6 times daily. (1 teaspoon of dried sage per cup of boiling water, steeped in a covered ceramic pot or cup for 15 minutes)
* slippery elm bark powder, soothing and healing. Add 1 to 3 teaspoons to food(for example, sprinkled on porridge or mashed in a banana), three to five times daily
* tincture of myrrh as a mouthwash: add 5 drops of myrrh (Commiphora molmol) to a quarter cup of water and rinse the mouth thoroughly three to four times daily.
