they don't go away.. but it's easy for a doc to clip them off.. they actually do that, they might give you a little shot first.. and then yes, they use some shape scissors and do it... at least in my case.. and one doctor (I don't necessarily recommend this at home :) but did tell me it could easily be done at home.. TRUE story.. :) anyway.. I have to say, when younger and bolder and dumber.. I did try it, and it worked... now, I don't know if I would do that..
They tend to pop up where material rubs against the skin.. like the abdomen where pants may press or around the neck, where a collared shirt may rub or even around the bra strap area... I don't like the sight of them and had mine removed... go to a dermatologist, they see that stuff all the time, they are VERY common... good luck
