Hi, I Banged The Crap Out Of The Inside Of

Hi, I banged the crap out of the inside of my ankle, the medial malleolous I believe, and I walk all day at work, I've been icing it, and keeping elevated, but I wake up in 5 hours, so was wondering if there are any stretches or something to do to get the blood flowing? I do have a pool. Thank you for your time. Sincerely, Mike Hulyo
