it is prob. a cankor sore

Canker sores r painful, internal mouth sores. Also called aphthous ulcers, they form on the soft parts of the mouth, such as the inside of cheeks & on the tongue. They r different from cold sores which form on the lips or outside the mouth.

Although the true cause of canker sores is unknown, they r NOT caused by the herpes simplex virus & r not contagious.

Those who r afflicted with canker sores know that they r painful & cause restrictions in eating certain foods. Here r a few suggestions to help deal with this condition

It is an inflamed taste bud. l get them all the time, & in fact l have one right now.

Lots of things can cause them, most commonly stress and/or eating a lot of sweet, salty or acidic (sour) foods. Besides the pain, they're not a big deal, & there is really nothing u can do but wait them out. It will take a day or two to go away.

If u get them frequently, see if u can trace them to certain kinds of food ( l can not, but some people can). If u can, see if reducing ur consumption of those types of food helps.
