Why does your Achilles hurt at first⦠but feel better once you warm up?
Most runners assume that early pain means the tendon is damaged or getting worse.
But the real reason is much simpler:
When youāre inactive, the tendon stiffens, fluid shifts, and the nervous system becomes more sensitive.
So the first few steps feel rough.
Once you start moving, the nervous system stops overreacting and the tendon acts as a sponge squeezer - pushing fluid out.
Itās not because anything healed instantlyā¦
ā¦but because tendons respond to load, consistency, and gentle motion.
The takeaway:
ā
Warm-up pain is normal. And itās something you can train through ā with the right plan.
