White lump on the left side of my throat/esophagus and close to tonsil?!

Okay, I have an appointment with my primary for tomorrow!. I was randomly looking in the mirror, and stuck my tongue out!. On one side of the throat left to my tonsil I saw a white lump!. My throat has been burning (kind of like acid reflux but not as bad) so I wrote it off as that!. Now I see a white bump, lump, something on one side of my throat!. It's not on my tonsil, but to the left of it!. Any idea of what that could be!?Www@Answer-Health@Com
