Open Question: Are these shin splints? How do I get rid of them?

Okay, well, I'm a 17 year old female... I have had these bumps on my shins for a really long time now, but I never really worried about them too much, but now that I am getting older, I am wanting to get rid of them, also when I walk for a long time, my shins start to hurt, not my calves, but my shins.... So I did research and apparently they're shin splints.. But shin splints are caused by running, I don't run at all, maybe about 5 years ago I used to run a lot, but not anymore... Anyway, could they still be shin splints? I've had them for years.. How do you get rid of shin splints? Thanks.
