Got stung by chopstick spikes, and now it’s under my skin. What do?

So I was eating out on Friday and since the chopsticks didn’t split evenly and had a lot of spikes on them, I tried to clean them off by rubbing the two chopsticks against each other as usual. I wasnt so careful and got stung by one of those little spikes, and didn’t realize at the time a small portion remained under my skin.

I didn’t notice any pain yesterday, but today it hurt for only a few moments and it’s honestly not bothering at all, but I then shined a flash light and saw the spike underneath my skin. I couldn’t get it out with the tools I had, and I wonder if I should see a doctor. If so, what kind of doctor should I see? A 外科医? Or should I go to one of those smaller clinics? I am new to Japan and not very sure about seeing a doctor here, but I can speak some Japanese, at least I am able to describe my situations and symptoms, if that helps too. Any advice would help, thanks in advance!

P.S. I think it’s time for me to get one of those bento chopsticks to carry around with me.
