Re: Is it possible for a cut to close up but still haven't healed inside?
It is possible for a cut to heal on the surface with a foreign body or collection of blood or pus underneath. That will cause continued pain, redness, swelling and possibly oozing out of cut. Some glass is radioopaque, meaning it will show up on xray. I would get an xray of your finger so if there is glass inside, it can be removed. Otherwise, it will continue to hurt and stay inflamed until it comes out.
