I just noticed a few days ago that it had felt like I had something in the back of my throat. I opened my mouth and notice a red bump on my tonsils.... Never had this before. The week before I had bad swollen glands, and now I noticed this on my left side of tonsils, size of a pea. But it's so annoying, every time I swallow I feel it, or when I turn my neck I feel it!! What could it be?? Please help, I think I'll call a doctor tomorrow.
