I had recently spent a LOT of time with a flashlight looking down my throat from July to December (had a mucus retention cyst that I diagnosed from the internet - I am TOO afraid to go to a doctor!) Anyway, I would check it multiple times a day to make sure it wasn't getting any bigger or getting infected. It did drain by itself and my 2 sides are not the same, never were, I never thought anything of it. I can't DESCRIBE the differences, but both sides (the tonsils and AROUND the tonsils aren't mirror images) Especially If you have a sore throat ONE side will look worse than the other and even healthy will look different. (I can see the bottom of my right tonsil, but the left one blends in to the bottom, it looks like there is extra skin on one side and not on the other, the right tonsil has a crater in it, left one doesn't - see what I mean? (I have VERY tiny tonsils and you can't see them at all unless they were inflamed, and when I DO have a sore throat I can see the right one, not the left one.) And you noticed all this 2 years ago?? You wouldn't even be around to POST if that was cancer!
