Lump on my left rib

[VamosityShaer]

So Monday 16, 2016 I was playing soccer at soccer practice, and I was out playing goalie. When I went to dive for a ball I fell on my rib cage (You're suppose to do this to help break the fall) but this time it hutted and like shortness of breathe so I concluded its a rib fracture, Next day I went to doctor get a X-ray to show If id had a fracture, it turns out it wasn't a fracture. I went home until Saterday 21 when I was about to sleep I felt a lump on my left chest and that was the spot where it was hurting before and it was definitely there and it hurt. I'm not sure why maybe if my bruised rib because it still hurted to breathe before that and lay down it hurted. What is causing this Lump? Is it because of what happen to me at practice? I need answers help

It's not hard to breathe unless I take deep breathes and it hurts to lay down on my back or stretch. I a very hard lump like it's part of the bone,
