What Causes Calf Pain? 13 Common Causes (You Should Know)

Achilles Tendinitis 

Achilles tendinitis is a common condition that can cause pain and stiffness in the heel, lower leg, and ankle. The Achilles tendon is a thick tissue band connecting the calf muscles to the heel bone. This tendon is used when walking, running, and jumping. Overuse or injury to the tendon can cause it to become irritated and inflamed. Achilles tendinitis is often seen in runners and other athletes who put repetitive stress on their feet and legs. The condition can also be caused by shoes that do not fit properly or provide enough support.

Initially, Achilles tendinitis may only cause mild calf pain and stiffness. However, the pain can worsen over time and become severe. Other symptoms of Achilles tendinitis include difficulty walking, swelling in the calf muscles, and tenderness when touching the affected area. 

Achilles tendinitis is usually treated with a combination of rest, ice, and over-the-counter pain medications. In some cases, physical therapy or steroid injections may be necessary. Surgery is rarely needed to treat Achilles tendinitis.
