I landed on somebody's foot while playing volleyball and twisted my ankle exactly 6 days ago. For 72 hours afterwards I iced and elevated religiously. I've gotten a ton of rest as well. But for some reason the swelling has stayed about constant since about day 3, which was worse than day 2. No pain whatsoever, but I've been taking ibuprofen to keep the swelling down. I'm told it shouldn't be so swollen anymore.. what else can I do?
