I have a white pimple inside my lower lip, what could this be?

It is painless and it started when a clear fluid which grew in 1 day turned white next day. It is not painless and it has been about a week, what could this be?|||Make up your mind, is it painless or not painless?|||It%26#039;s a fever blister, or a canker sore inside your mouth. My grandma always called those %26quot;lie bumps%26quot;. Then she%26#039;d ask what I%26#039;d lied about! lol...anyway, there is an easy home cure. Buy some alum in the spice section of your supermarket. Wet your finger and put a dab on the spot. It will make you pucker and mouth water, but it will go away quickly after a couple of treatments. I get them from eating acidy foods, especially fresh tomatoes in the summertime. But a lot of people get them this time of year.|||just a pimple|||it is a kanker sore it should go away on its own but if it doesn%26#039;t and if it does not go away in another week you should go have it checked out|||herpes|||it is probably an ulcer, if it is try bonjela|||Cancer|||Well it could be that you ate something hot and it burned your inner lip or if you performed oral on a girl that was not clean she couldve gave you something if it does not go away in several days contact you doc|||herpes?|||Well if it doesn%26#039;t hurt then it wouldn%26#039;t be a cankersore. It could be a zit...not to be rude..could it be a std?|||herpes dude,, dont worry everybody will get it|||something gross... or maybe just a herpes cyst,,, better tell your bf so he can be checked also,,,,|||herpes.|||First of all it%26#039;s not a pimple.....|||Uh, if it%26#039;s %26quot;not painless%26quot; then it%26#039;s painful, and I%26#039;d say you have a canker sore there, bud.|||sounds like a bad, infected pimple or cold sore. try to keep it clean and don%26#039;t pick at it; it will go away.
