Google Alfredson technique for Achilles Tendonitis and do it.
Add to it Deep Heat massage am, 20mins ice post exercise (and regularly throughout the day), possible heel raises, check wear on your shoes and get your rear foot mechanics checked, stretch regularly.
That should do it.
Cheers Jacko. HAve done much of that in the past, but have been a bit slack recently... Will look at it properly, then start doing things a bit more regularly :)
Consistency is paramount for it to work well. If you do it all things should improve.
From a physio perspective adding in glute medius strengthening will help to as it reduces internal rotation moments of the leg. (which drive an increased pronation moment at the sub talar joint)
