I hurt my arm when running out a door, hit the door frame so hard. I didn t apply any ice pack and now there s a decent side lump under the skin (about the size of a whole thumb. It s not super hard lump, it s kind of between hard and soft (bouncy?) and moves when I press on one side. It s not very painful to the touch. What can cause this? And how long does it take for the lump to go down?
