I am a 22 year old female. I have had purple/red veins/lines on my tonsils and in the back of my throat. In the past couple of weeks, I have had a feeling of something in my throat/a dry throat that could be swollen, a strange sensation with zero pain. I have a white cover over the back of my throat/back of tongue. My tonsils are swollen for awhile and large crypts with a couple of (what I think) are tonsil stones. Most worried about the veins.
