today, i was recently biting my thumbnail to get off a hang nail right before lunch around 1:30, gross i know. and ever since then only on the left side of my throat feels like something is poking it or is stuck there. ive looked there and theres seems to be a scratch not on my tonsils but that flappy part and is red. idk what it's called. but it is really irritating me. theres also yellow like bubblish things on my palate. and this morning i woke up woth my left side of my neck sore, i think thats just cuz i slept on it wrong. can anyone give me advice or have had similar things to this?
