Glass help?

I was smart enough to break a pane of glass about a week and a half to about 2 weeks ago, and Now one of the wounds HURTS LIKE FUCK!
I had a cut and 2 hole looking things, but the cut and one of the holes healed up 90%, the other hole is purple, it pokes out, and Whenever anything touches it, it feels like there is a shard of glass in it.

I’m not a pussy, so when I say It hurts so bad that I am ready to cut open my hand to get it out (if its there, which I am about 93% sure it is), I mean it.

Does anyone have ANY advice?
