Achilles tendonitis is an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. It is common in runners and middle-aged recreational athletes.
See a doctor if you feel a sudden pop in the back of your ankle, as this may indicate a tendon rupture.
Connect with a doctor, physical therapist, or imaging center near you.
