Quick summary: I injured my ankle playing basketball 8 days ago. I rolled it, classic ankle sprain with swelling, blue/purple bruising and some pain. For the next 4 days I mostly followed the classic RICE therapy (rest/ice/compression/elevation - it was hard to keep the ankle elevated during the day.) Also used sodium naproxen 2x day. Days 3-5 I started using heat (2x day). On Day 5, pain was gone (swelling down, but not gone), so I figured I'd go out for a run and stop immediately if it hurt. Good news - no pain, so did 6 "easy" miles (9:45 pace). Bad news - Dial forward to Monday, and my ankle & foot are swollen, even more bruising and it hurts! I resume RICE (No heat). Past 2 days aren't any better. OK, I realize I'm a knucklehead. So, how long do I continue RICE before getting medical advice? Thanks in advance.
You can do Ice for 72 hrs with no problems, I suggest you see someone asap. why? well you may have injured a tendon or worse ruptured, brusing is bleeding under the skin, and xray or MRI could determine the extent of the injury and what course of action to rehab. your injury. I would elevate the foot, compression wrap (ace) stay off it, continue to ice and seek medical attention.
Sorry to hear about the roll. Here's an article with some info that might help once you get past the PRICE phase http://www.p2sportscare.com/pain-relief-huntington-beach-ca/how-can-this-help-my-injury/ankle-sprain-treatment-orange-county/
I would recommend to see a doc or therapist to apply any of the advise though.
