What's weird is the appearance and location. It's a white mark with kind of a jagged edge at the top, and is underneath the tongue, like down towards underside of mouth, not on the tongue or lips itself. It's extremely painful to eat or move my tongue around. I'm not sure if it's a canker sore based on the locations and appearance.
Been using Orajel Gel to numb it past two days, but it doesn't do anything, just wears off and is still painful. Been like this for 4 days, and have never had a history of something of canker sores or cold sores.
Could it be Candidiasis?
