Hi, I Was Just Hit In The Leg With A

Hi, I was just hit in the leg with a baeball while running to first earlier this evening in a softball game. It was pretty hard throw and hit the ground and then bounced up to hit right under my right knee. It immediately swelled and felt hot to the touch. I now can see a raised area with brushing continuing to developer. This evening I am having trouble putting weight on it without experiencing pain. Just want to check that I shouldn't be looking for anything other than bruising and a little pain. I want to make sure I shouldn't go in to get it checked for anything else... Break etc. i
