Treatment for Under Eye White Bumps?

I have hard white bump like pimple on my face. They are mostly under my eyes they are very tender and they swell and become imflamed.

I've taken a needle to they and they keep coming back they are large and my fellow high schools students are asking what are they? I had these for years and my identical twin also has these hard white pimples under her eyes a well. What do you suggest I do?
