What should I do about this shard of glass that's been stuck in my big toe for about a year?

About a year ago, I slipped and fell while I had a glass of ice water in my hand and of course, it broke and shattered everywhere. While I was trying to clean up the glass, a little shard got lodged in the side of my big toe. I tried pulling it out, but had no luck. Eventually, it healed up with the shard of glass inside and I hardly thought about it again. Now, a year later, I can feel it surfacing. If I step on it just the right way, I feel a little sharp pain.

So, should I try cutting it open and pulling the glass out, or just wait for it to expel itself?
