I noticed a few days ago that I have some holes or tiny folds in my tonsils with white stuff inside. I haven’t been sick recently and they don’t hurt at all, and perhaps it’s always been like that but I only just noticed because I only bothered to look back there recently. Is this normal? Like pus or just food buildup? I took a q-rip and swabbed and some came off but it just comes back after I eat. I’ve also never had tonsillitis.
