A shelf slid out of the trunk hitting my leg between the ankle and shin. I iced and elevated it for 3 hours only getting up to use the restroom and get something from the kitchen. After the 3 hours I stood for 15-20 minutes getting ready for bed. I put some aspercreme on it avoiding the area where the skin was broken and went to bed. I stood up to put a fan on and it hurt so I looked down and it had swollen to the size of a tennis ball.I elevated it all night and iced it a few times. The swelling has gone down a lot, though still very swollen, but it burns when I stand. Should I be concerned enough to go to immediate care?
