Whilst downclimbing a 4a today (I've not got up it, do I still get the tick? :wink: ) I jumped off, and because my mat was elsewhere, landed on the ground. The landing wasn't bad, just tilted, and I bent my ankle back pretty bad. It hurts a bit walking on it, so I know it isn't broken, but is there anything I can do to stop it becoming a full-blown injury?
