Tendonitis and tendinopathy
Pain and stiffness at the back of the heel, often worse in the morning or after activity. Most cases improve with a structured loading program, footwear changes and time.
Ruptures
A sudden pop and weakness pushing off. Some ruptures are treated in a boot; others are best repaired surgically. The decision depends on the tear, your activity level and timing, so get seen quickly.
Common questions
How do I know if I tore my Achilles?
A pop or feeling of being kicked in the back of the leg, followed by trouble pushing off or standing on your toes, is typical. Get evaluated promptly.
