What?
I get these lumps on my lip almost constantly, they are hard to burst (though this one looks riper than most) and by the time they've died down I usually have another one. Prime placements are here, or right hand near corner, or top left near cupids bow.
I know it looks like a white head but it won't burst. Previously I've popped a needle in which has helped but can't be good to do all the time!
I don't think they're cold sores - no tingling or scabbing - but Google will only give me that answer.
Any ideas?
