To be honest I'm not really sure what it could be. Yes it could be warts. And some types of those can be treated. (Maybe all types??) There are other things that it could be though. That's why this type of question is so tough for anyone here to answer. People have called these ingrown hairs, pimples warts, little bumps. Most of the time they say the exact same thing, they describe them as looking the same even. Then later on we find out they are all different. Some are warts some our pimples, the last one turned our to be an ingrown hair possibly.
I'd guess if you were to talk to your Doctor on the phone he may not be able to tell you what it is either without actually looking at them. But you never know.
It's possible these are warts, but it's also possible it's something else. Sorry I know this doesn't help you much. But without actually seeing them, it's hard for anyone to help too much. And please remember, we're not doctors, just regular people like you'd meet on the street, trying to help each other out whenever we can.
