Will The Bumps Formed After Bleeding Due To An Injury On Lips Heal By Themselves?

Hi, a few months ago (let's say in september or october) I was playing around when suddenly I got hit in my lip. It hurt immediately and then I noticed it started bleeding. Right away I ran to the bathroom and noticed it was swollen and there was a cut on my lip where I guess it got cut my tooth. For a while the swelling and the bruising stayed and the cut had formed a scab. Now everything seems almost normal again, except I have a lump on the inside of my lip where the cut was, which is visible sometimes because it bumps out. Will that ever go away? Some days it seems smaller and less visible and some days not so much. I never got stitches I just let my lip heal on its own. Please help!!!!
