I Lifted Weights Tonight At The Gym Tonight. When I

I lifted weights tonight at the gym tonight. When I got home I noticed a large hard lump on top of my right foot, about an inch away from my ankle. It doesn't hurt but it is rather hard and there's a separate second lump next to it. The top of my foot looks a little puffy but not too bad. I can walk just fine and it doesn't hurt thank goodness. Have I ruptured blood vessels? What would cause this to form such large knots after weightlifting. I really pushed myself at maximum weight doing sitting leg press. Maybe this was too much pressure on my feet?
