how long before eccentric raises will clear up achilles problems?

turbo bump

In about 2-3 weeks improvements should be noticeable. I'd stop running for at least a week or two - running is what damaged it, and now you are providing something very intense to the Achilles (eccentrics), and by running you are not allowing it to recover. Some people can do some light running during it, but based on what you said, I think you should stop and just do the eccentrics.

Do something to warm-up first (hot tub, light repetitions of it) and it is okay to ice afterwards. 15 may be too many reps - you can do a higher weight with fewer reps.

Good luck!

You should probably calm down on intensity of calf exercises. The eccentric drops help with flexibility in your calves and assist in proper healing of the tendon. The exercises don't magically fix the tendon. I think Achilles repair takes on the order of 90 days or so. That means you need to do the exercises for a long time at a moderate intensity. Unfortunately you need to cut back on your running for the period as well to allow the tendon to heal. It took a few months to finally kick the tendon problems for me.

As a follow-up, I did immediately ease up on the intensity of the eccentric exercises but it was too late. By that time it was hurting me to walk and several weeks later the AT does not feel much better. Clearly, as in my case, it is possible to make your condition worse with the heavy-load eccentric exercises exactly as specified by Alfredson (i.e. 3x15 reps, straight & bent leg, causing pain in the tendon). I did this for about 4 weeks before I had somewhat disabled myself.

I was under the impression that it's supposed to get worse before it gets better, but it just seemed to keep getting worse until I could not walk without pain throughout the day. I don't think this is what they had in mind.
