yea i get those.. infact i just got over one like last month, it was inside my upperlip on the right side. It was really a bad bitch to handle, it felt like a wasp was stuck up in there and kept stinging the same spot, thus i was a pretty silent person during that because any move of my mouth could potentially result in hell-raising pain... I found that Peroxide is your best friend with those, all you got to do is soak a cotton ball and stick it where the sore(s) is at, leave it there for about 10-15mins., it might sting at first but it will make it go away faster than going without it
