Is a tooth pushing on/near it when you lay down. This can
cause a slt papule to form & come/go. People w/ a bite problem
chew different & rub against inside tissue & this can show up.
Is it clear/red/purple? We've all bit our cheek while eating
& this can form a papule. Depends where in mouth but may have dentist take a look to ck. This can also be a response to a
silver filling or a point from a tooth rubbing. If it's only
one & comes/goes, have a look-see!
A papule can be like a pimple and may "pop" and drain. When it recovers, the puss or fluid will return and build up until it again "pops". If this is the case, then it is not "going away" and it's not getting better. You don't know what it is or what is draining down your throat. It needs to be assessed by your health care provider, or get a referral to see an ENT. If you are in the nursing program, have one of the nurses take a look at it, too. Good luck
