Your Achilles Doesn't Need Rest. It Needs Load.
Why 'wait until it stops hurting' keeps failing runners with Achilles pain, and what the research says to do instead.
If your Achilles flares every time you build your mileage back up, the problem usually is not that you need more rest. The tendon lost its capacity, and rest does not rebuild capacity. It quiets the pain, the tendon stays weak, and it breaks down again on the first hard run.
I broke down a tendon-lab study that changed how I bring runners back from Achilles pain, along with the exact loading progression I use and where shockwave and EMTT fit in. It also covers the difference between mid-portion and insertional Achilles, and how to actually know you are ready to run again.
