I found a couple of tiny tonsil stones (rice sized) after investigating a feeling of a lump in my throat when I swallow, I removed them with a cotton swab. Was wondering if this is dangerous to have removed them this way? Are stones of this size and of few quantity normal? Applied some pressure and they popped right out. No pain with them in or after/during removal. Also I feel like there is a tonsil stone on the backside of my tonsil, but im not able to see behind it- how should I go about investigating the existence of one there? Thanks!
