Morning stiffness
Stiffness after rest that warms up with motion but returns after activity can occur with tendon overload.

Achilles tendon pain
Achilles pain may build with activity or appear suddenly after a jump, sprint, or misstep. Location, onset, strength, swelling, and the ability to push off help distinguish tendinopathy from a partial or complete tear.
Where and how it began
The Achilles tendon connects the calf to the heel and helps lift the heel during walking and running. Pain may occur within the tendon or where it attaches to the heel bone.
Stiffness after rest that warms up with motion but returns after activity can occur with tendon overload.
Tenderness or thickening may develop several centimeters above the heel.
Pain at the back of the heel may be aggravated by shoe pressure or uphill activity.
A snapping sensation, rapid swelling, and difficulty pushing off can indicate a tear and need prompt care.
A focused tendon assessment
The examination may assess the site of tenderness, swelling or thickening, ankle motion, calf strength, walking, the ability to rise on the toes, and specific tests for tendon continuity. Ultrasound, X-rays, or MRI may be considered when findings make them appropriate.
Rule out a partial or complete rupture when symptoms began suddenly or strength is reduced.
Separate midportion tendon pain, insertional pain, bursitis, and other causes of posterior heel pain.
Identify recent changes in activity, surfaces, recovery, shoes, and calf flexibility.
Progressive loading, not guesswork
Achilles recovery is often measured in months rather than days. Aggressive stretching or strengthening is not appropriate for every stage—especially when a tear has not been ruled out.
Do not walk off a suspected rupture
A sudden sensation of being kicked in the back of the ankle, a pop or snap, new difficulty walking, inability to rise onto the toes, or a visible gap in the tendon requires prompt medical evaluation. Until evaluated, avoid pushing through the injury.
A rupture can sometimes cause less pain after the initial injury even though strength remains impaired. Loss of push-off matters more than pain alone.
