Have you ever noticed a really sensitive part on your tongue, and when you look in the mirror, there's a little bump?

I call them "enlarged taste buds." I've also heard them called "tongue zits," "lie bumps," "tongue blisters," and "inflamed taste buds."

They are extremely common, and they can happen when there is trauma to your little tongue. Eating spicy, acidic, hot, or hard foods can cause local inflammation. Allergies and biting your tongue can also irritate your taste buds.

The inflammation looks like a tiny white or red bump. It's different than a canker sore, because those are usually found on the inside walls of your mouth, and the sores are generally bigger, more irritated, and open.

If your tongue isn't back to normal in 7-10 days, you should definitely go see your doctor to get it checked out.
