Fezley,
Do you have anyone who can take some pictures of the lesion? My husband and I photo-documented my tongue lesion while we were waiting for a biopsy. It ended up being especially helpful because my surgical oncologist could see what the lesion looked like before I had my excisional biopsy by the oral surgeon.
I think this is a good idea because then you can show the ENT exactly what you mean. It's important that you use good light, such as a flashlight. You may need to use a piece of gauze or paper towel to grip your tongue and pull it over if it's in a conspicuous place. This is why you need someone else to take the picture(s). One to use the camera and hold the light and you to manipulate your tongue. If the lesion fluctuates from day to day, you may want to take a series.
Best of luck and here's to hoping it is only an infection!
