Q: I have what my ear, nose and throat specialist diagnosed as tongue fissures. I get a bright red burning tongue covered with little fissures. This occurs mainly when I eat or drink, though hot and acidic items, such as soda and cured meat, seem to really aggravate the problem. My doctor prescribed an over-the-counter mouthwash and Prilosec (stomach-acid reliever), but the problem persists. Is there anything else I can do? - S.L., Breese

A: Tongue fissures occur in about 5 percent of the population, says Dr. Bruce Haughey, professor of otolaryngology at Washington University and Barnes-Jewish Hospital.

There are two types: congenital, which are inherited, and inflammatory, which can develop later. Sometimes the inflammatory type is related to a systemic disease. Haughey recommends that anyone experiencing these symptoms see a doctor to determine whether a biopsy is needed, just to make sure there is nothing more serious going on.

But for some, just the pain of tongue fissures is serious.

"It can be quite debilitating if it prevents eating," says Haughey. "And it can be very painful."

Now for the bad news: The best thing you can do for your tongue is to completely stay away from anything that triggers the inflammation. Haughey also suggests looking at any other medications you are taking; some drugs, especially cardiovascular medications, can irritate the lining of the mouth.
