Have you considered seeing someone qualified in myofascial release/trigger point therapy/or reflexology? Especially with something as your describing, the pain could be coming from certain muscle groups being far too tight and just needing releasing (relaxing)...
If you run your hands over different muscle groups on your body, you'll be able to feel the difference (between loose and tight muscles) yourself and see if perhaps this may be something that you could benefit from... Tight muscles, besides feeling hard to the touch, will feel as if they are rough or covered with small grains of rice... If you rub these out (pardon the parlance) you'll feel the muscle begin to smooth and relax. Relaxed/Healthy muscle will feel soft and pliable... In this way, you can begin to work your way deeper into your body from the surface down, slowly releasing the tension in the muscles and allowing your body to perform at its best.
Be wary of using too much pressure... while it may feel good at times, it is not beneficial, and can actually make things worse. Often, with your mind properly focused on the muscle and the tension, the lightest sustained pressure is all you need to begin to release these muscles.
In terms of trigger-points, you may find in your exploration that you come to a particular point that feels particularly painful/sensitive and radiates pain to another point in your body... These are areas where great amounts of tension have been built up... Using *very* gentle pressure, and for no more than 8 seconds, you can press on these points to begin to open up areas in your body. If you feel the point hurting more, back off and return to it later. If you release these points properly and are in tune with your body, you can feel these blockages being swept away, circulation returning to these areas... You'll also notice that these areas feel lighter than before...
This is nothing but the briefest of overviews, but I think it's enough for you to do some testing (should you choose to) on your own to see if you can finesse some harmony back into your ankle. Books are also enormously helpful in this regard, though nothing beats seeing a trained professional.
good luck.
