Achilles tendon acquires its name from a Greek mythological story. Achilles was a fearless Greek hero, who became immortal after his mother; Thetis dipped him (holding him by the heel) in the magic waters of Styx. The heel remained vulnerable, and later he had a fatal heel injury in a war.

What is Achilles Tendonitis?

Achilles Tendon is a fibrous band of tissue connecting the calf muscles to the heel bone. It helps transmit the pressure from the lower leg muscles to the foot. Pain and swelling of this tendon is known as Achilles Tendonitis where "itis" means inflammation.

What are the Causes of Achilles Tendonitis?
  • Obesity: Achilles tendon bears thrice the body weight during body movements and being overweight increases the burden manifolds.
  • Overuse trauma: Rapid increase in daily activity with repetitive stress on the feet. Sports persons are at a greater risk of developing tendonitis.
  • Anatomical abnormalities: Flat feet, hyper-pronated arch, frail or tight tendon and calf muscles.
  • Lack of stretching exercises
  • Accidents or foot injury
  • Unsuitable footwear: High heels, shoes without arch support, heel support and cushioning.
  • Arthritis: It being a musculoskeletal ailment, tendinopathy can be sign in addition to other symptoms of joint pain.
  • Medications: Quinolone drugs cause inflammation of the tendon.
What are the Symptoms of Achilles Tendonitis?
  • Pain: Site of pain is above the heel bone at the insertion of Achilles tendon and small region around it. Pain tends to decrease with mild activity after a period of rest. However with increased motion the pain worsens.
  • Swelling: Inflammation causes tenderness, warmth and swelling near the tendon. Occasionally swollen calf can be a symptom.
  • Restricted movements: Due to limitations in plantar flexion of the foot, running, climbing and standing on toes is stressful.
  • Limping: Stiffness and weakness reduces mobility.
How is Achilles Tendonitis Diagnosed?
