Hello, while recently looking for tonsil stones I noticed a couple of lumps on the skin behind my tonsils (I'm not sure what that area is called?). I've had the feeling of something in my throat, so that is why I was checking for the stones. I didn't find any stones, but I'm curious about the lumps. They don't hurt, per se, but I'm not sure if they're supposed to be there. I've had heartburn for the past few years, could that be the cause of them? I though maybe cancer, but with 3 separate lumps a few centimeters apart, that didn't make a ton of sense.
I've uploaded an image to http://i.imgur.com/lSJfvKV.jpg though they are kind of tough to see, I circled them.
Any insight would be appreciated.
