I am a 16 year old female, 5 feet 4 inches tall, 120 pounds. Today I noticed an irritation near the back of my throat, upon further inspection, there seems to be an extremely red bump with a white head on the right side of my soft palate at the very back on the flap of flesh that comes just before my throat. I'm a little concerned because it is painful and is interfering with eating and drinking. Do you have any idea of what it could be and if it is dangerous?
