I have a bump on my foot which appeared after I steped on glass?

So 2 weeks ago exactly I stepped on a big peice of glass. I put peroxcide on it and kep it bandaged. The wound has healed great and the bruising is gone however there is still a bump right where the cut is. It has been there the entire two weeks with no changes. Its not discolored and it really doesn’t hurt to put pressure on it. I can walk on my foot but it just getts annoying becasue I can feel the bump when I put shoes on. What do youthink this could be? If it doesn’t go away by next week I am for sure going to the doctor I was just wondering as to what it could possibly be.
