Achilles tendinitis is an overuse injury of the Achilles tendon—the band of tissue connecting calf muscles to the heel bone. Calcaneal spurs (heel spurs) and plantar fasciitis involve chronic inflammation and bony growths under the heel caused by repetitive stress, poor foot mechanics, or improper footwear.
Common Symptoms
Intense heel pain during the first few steps in the morning · Aching or tenderness along the back of the leg or heel · Bony bump or sharpness felt under the heel bone · Stiffness that improves with light movement but worsens with heavy activity · Swelling that increases throughout the day
