Here is what I posted in another forum about AT. I have been dealing with it for the four years of my college career now. I have found that professionals offer no assistance (at least in my area).
Stretch your calves, roll your calves, strecth them again, repeat forever. It's a tough issue I have been dealing with for years now. I suggest doing the toes on the edge of the step and letting your heels drop method.
Also, ice it like a mother. Take Aleve (try ibuprofen too if you prefer). Honestly, only Aleve was able to bring my inflamation down.
At night and whenever I am sitting I wear a foot brace. (

) This prevents the tendon from relaxing and then tearing when I try to walk. Also, I never walk around barefoot. I always have shoes on because it has an elevated heel.
At first, I tried the strengthening approach, but it just got worse and worse until I really hurt myself and I had to hang up the shoes for 3 weeks. I think if you do all of the above, you can maintain it, but I honestly believe (after receiving no help from a myriad of professionals) that it is just a bio-mechanical issue that we were born with. No fix.
Yes, I am running. My achilles is permanently swollen. I built up a large bone deformation on my calcaneous because I ran through it for so many years. I have to slice the back of my shoes to make room for the size of the back of my heel. The swelling will most likely keep returning with increased training. It's something we have to deal with, or get surgery. I may get surgery after my senior year.
My achilles is getting better (I hope). At least it seems that way. Gentle stretching about 20x a time is helping. I will VERY VERY VERY VERY SLOWLY begin to stretch it, reach a tightness and hold for 30s, then slowly slowly go back to neutral.
It must be equal in length/flexibility to your other achilles or you will have even more problems. Don't be concerned about its size, but rather how it feels/flexes. Also, don't press it or squeeze it.
