Achilles tendonitis

Last november I ruptured my left achilles tendon and needed surgery to repair the damage. Amazingly I was off crutches by mid January, undergoing physio and light gym work by Feb. Not bad I thought.

So to my problem. The left achilles is now fairly much healed. After a good warm up I'm confident that it will hold up to more or less anything I can throw at it, I've even had a game or two of squash without much discomfort. My main concern is my right achilles. It transpires that I have a history of scaring and now suffer from tendonitis. Reading up on the net, the only treatment I can find is rest or surgery. It had the best part of 3 months rest and that didn't help much and there's no chance of surgery until a rupture occurs - and I REALLY don't want to go through that again. I've bought new running shoes and try to wear padded running socks to provide as much protection as possible, but I still feel discomfort after about 5 mins of running. I hate running with a vengence, but maybe it wouldn't be so bad if my body would just get on the programme!

Any ideas how I can overcome this?
