I have red spots on the roof of my mouth, but not in the middle. I can t really see them, but my husband says they are clustered, but do not look like blisters.. The spots started near the back on the right side, and has now spread to the front behind my teeth on the right side.. They are painful, and my lymph nodes in my neck are swollen. It is hard to eat, and my gums bled when I brushed tonight. I have three kids that are sick this week, one with the viral form of strep throat. What could this be?
