I have had an allergy related cobblestone at the back of my throat for quite some time now. It would swell up, then decrease in size. Starting yesterday, it increased in size and turned white! It is almost completely white this morning! Is this just a sign of white blood cells attacking an infection of some sort? Anything to be overly concerned about? The only other sympton is just feeling it more than usual -- it is not causing a sore throat.
Thank you for your comments.
