I was given too much Levaquin http://well.blogs.nytimes.com/2012/0...-effects/?_r=0 before the black box warning and one of its side effects is having the Achilles tendon rupture ! Fortunately, mine did not (yet). I can truly say I am sorry for your pain. I did not know anything about the Achilles tendon or even think of it when I had my pain and when I told the doctor my "ankle" hurt he told me I was getting old (I was in my early 50s). It caused all kinds of things that are permanent health problems still, now.

I don't know much about it though except that I believe your doctor with the operation problems, I have read/understood that and mostly that it is a very very long debilitating recovery after messing with that tendon. You literally cannot walk. My knees are in bad shape with arthritis but I do not think I will ever get them operated on (I have asthma and other problems that would make any operation risky) so I am working hard to find what eating, drinking, exercise, usage, vitamins/minerals, etc. help most or make them feel worse, etc. and slowly (too slowly :-) working to do things that make things feel better and less things that make them feel worse.

Maybe some of these exercises could help?
