Hi Nicola,
I can sympathise with your situation whole heartily. I'm in the British Army and have, for the last 18 months been medically downgraded due to my AT preventing me from running. I got the injury by increasing my weekly mileage in training too quickly. A fatal error on my part.
I've had regular physio which has included ultrasound, plenty of stretches on the calves and deep massage (also on the calves) using a foam roller (quite uncomfortable but very effective).
I also had my bio mechanics checked by the Podiatrist (not sure of spelling) and found that my feet were just not designed for running! (after 40 yrs). I have, as a result, had Osthetics made for my footwear which now seat my feet in the correct position.
I have, in the past 2 weeks started a 'Get back to running' plan on my Adidas micoach and fingers crossed am not getting any pain in my achilles.
During the time of not being able to run I worked on my core stability and worked hard 4 days a week on a rowing machine which not only stabilised my cardio output but offered a great stretch for the calf and achilles.
As in previous posts, my advice is quite similar but most important. Please please don't try and rush back to running. Believe me, I have been desperate to get back to it but have had to learn to be patient to the extreme. I think the trick is to find a replacement to running that can keep you motivated and look forward to when you can get back to pounding the roads again.
Good luck
PS. Don't let my 18 month lay off put you off. I'd suffered from calf problems and lower leg problems before and was told that because of this the healing of the AT would probably take a while. It was an accident waiting to happen apparently.
