Baby pimple on hand???? Should I be worried?

Gl

She’s had it a few weeks and I totally forgot to bring it up at her last appointment. It’s not painful, not warm, it’s never been red, and it hasn’t changed which is why I haven’t been worried. It’s hard and not puss filled. I’m not popping it nor tried to. It might be nothing but when I googled some people said MRSA?! It’s the only one too.
