If you’re an athlete or someone who frequently participates in running or jumping exercises, you’re likely familiar with Achilles tendonitis. This inflammation is often related to long-term strain on the calf muscles or a sudden increase in exercise intensity. You may also have heard people describe a sudden “kick” sensation during physical activity, which is a common symptom of Achilles tendon rupture. Let OneEssential’s physical therapists guide you through the symptoms, causes, diagnostic methods, and recommended treatments for Achilles tendonitis to help you manage the condition effectively.
Symptoms of Achilles Tendonitis
The most typical symptoms of Achilles tendonitis include pain, swelling, localized stiffness, and tenderness, with the pain usually concentrated above the heel and potentially extending up the calf. In severe cases, walking may become difficult. If you experience these symptoms, it could indicate Achilles tendonitis, and it is recommended to consult OneEssential’s physical therapists for stretches and strengthening exercises to alleviate the inflammation.

Achilles tendonitis can be divided into two types:
- Mid-tendon inflammation: This type occurs about 2 to 6 cm above the heel, which is the most vulnerable area of the Achilles tendon. Athletes are most likely to experience inflammation in this area.
- Lower tendon inflammation: This occurs at the point where the Achilles tendon connects to the heel bone, and it is more common in older adults.
Causes of Achilles Tendonitis
Achilles tendonitis is primarily caused by prolonged abnormal pressure on the Achilles tendon, especially during high-intensity sports or repetitive movements. Activities like running, jumping, or suddenly increasing exercise intensity place excessive load on the tendon, triggering inflammation. In activities such as mountain climbing or jobs requiring frequent climbing, the foot may bend at an extreme angle, putting additional strain on the Achilles tendon, leading to inflammation.
If you’re an athlete or a fitness enthusiast, consider consulting OneEssential’s physical therapists for a 1-on-1 session to help you design appropriate and proper stretching routines to prevent future tendonitis.
For older adults who rarely exercise but experience pain above the heel, it’s important to check for possible bone spurs. Bone spur formation can cause friction with the Achilles tendon, resulting in inflammation and pain.
Treating Achilles Tendonitis with Physical Therapy
At OneEssential, the treatment for Achilles tendonitis varies depending on the location of the inflammation. For inflammation in the lower tendon, which often leads to tendon hardening, physical therapists typically focus on stretching and strengthening exercises for the calf muscles. These exercises aim to reduce tension and pain at the affected area. This issue is less common for mid-tendon inflammation.
For both types of inflammation, we also use shockwave therapy and acupuncture to stimulate the inflammatory response, speeding up the healing process of the injured tendon. Schedule your 1-on-1 consultation today
