I ran the Edinburgh Marathon in 1983 with Tendons which were already causing me trouble in training. After completing the Marathon, I was unable to run or play rugby without major pain for the next 7 years until I had surgery on both my tendons, one of which was permanently fixed. The surgeon did say it had a 50% chance of working! Five years ago, I went to a new surgeon in the US to ask if he could fix the other and he said that the tendons were paper thin because of the previous scarring and my age and would not do it.
Why did it happen? I had proper new Balance shoes, I ramped up my training gradually, I was already a very fit rugby player in my early 20s. Two reasons given to me - it was the shock of the road running and recently I was told my a surgeon that I had somewhat flat feet.
My advice would be to rest for a long time and of course, you know what I'm going to say as you have probably already been told it - swim instead! If you're going to start running again - run on grass.
