so it turns out that i have bone spurs.
the doctor said that despite this i actually have very good range of motion.
there is nothing that can be done about it except surgery.
some things that i have found help to manage it are:
1. when landing precisions aim to land on the ball of the foot, the meatiest part. not right on the toes or front of the ball. i suspect this has to do with leverage. the further we land away from the ankle joint the large the force it needs to absorb and for some reason this tends to tweak it.
2. once again when landing precisions. Aim for stiffness in the ankle, As little dorsi flexion as possible. i suspect this maintains the gap in the ankle joint and stops the bone spur coming in contact with the lower bones.
3. With arm jumps the same rule with ankle stiffness. ALWAYS HAVE THEM STRONG, dont relax them, even if you are doing a sliding arm jump. the worst injury i have had to my ankle was when i expected to slide and my foot stuck to the wall. if you relax your ankles in anticipation of the slide then the day it sticks will probably hurt alot.
4. be really careful on the arm jumps at your limit. you are putting major force into the ankle and usually aren't fully focused on technique and more concerned with making the distance. The angles tend to change as well into something that has a higher likelihood of aggravating the problem. all you can really do is hope for the best, or just don't spend alot of time trying to do massive arm jumps, the choice is yours.
5. maintain range of motion. stretch etc. you can have them there and manage them so that they aren't as big an issue.
They will always come up from time to time when your concentration slips or just dumb luck.
Surgery is an option. i thin it was a 8 - 12 week recovery period. Plus you cannot really get it through the public system, you would have to pay it all yourself. uncertain of the costs. if i did it i would need both ankles >.<
wont be doing it just yet, will wait and see how i go over time
