I’ve had a persistent sore throat for about 2 months now. It’s been red, and it looks like there’s holes in my tonsils, but no tonsil stones. The back of my throat has also looked lumpy, if that makes any sense? My doctor took a strep and covid test, and the results were negative so she told me it was definitely just a cold, but I’m beginning to get worried. Please help! I attached images.
