Suggest Treatment For Pain In The Foot Caused By Glass Cut

2.5 weeks ago I stepped on a piece of glass on the bottom of my foot. The cut was fairly deep, but I didn't get it checked out. It seems to be healing ok I used neosporin. Its closed now, nothing has oozed out of it, and there is no red line..but it still hurts when I walk on it and even sometimes when I don't, Its not a lot of pain..but noticable. Is this normal? should I see a doctor?
