Causes, Symptoms, and Treatment of Achilles Tendonitis
The Achilles tendon connects the calf muscles to the heel bone and helps with walking, running, climbing stairs, jumping, and pushing off the foot. Achilles tendonitis (also commonly spelled tendinitis) usually develops from repetitive stress rather than one specific injury. It is common in runners and other active people, especially when activity increases too quickly or the tendon is being overloaded over time.
Patients often notice pain and stiffness in the back of the leg or heel, especially during activity or when getting moving after rest. Swelling and tenderness may also be present. Achilles tendonitis can affect the middle portion of the tendon or the area where the tendon attaches to the heel. When symptoms become more chronic, the tendon can start to thicken and show signs of degeneration over time.
Treatment often starts with reducing strain on the tendon and giving it a chance to calm down. Many patients improve with activity modification, ice, supportive footwear, physical therapy, and a gradual strengthening program. More persistent cases may need additional treatment.
Diagnosis of Achilles Tendonitis
Diagnosis usually begins with a discussion of symptoms, activity level, and whether the pain came on gradually or started after a change in training or routine. A specialist will examine the tendon for pain, tenderness, swelling, tightness, and how the foot and ankle move both at rest and during motion.
Imaging is not always needed right away, but it can be useful when symptoms are not improving or when the diagnosis is unclear. X-rays may help rule out other causes of pain and may show changes near the tendon insertion. Ultrasound can show how the tendon looks and moves, and MRI can provide a more detailed look at the tendon when needed.
Medical Management of Achilles Tendonitis
Many patients improve without surgery. Early treatment usually focuses on reducing irritation in the tendon and then gradually rebuilding strength and tolerance for activity. Self-care often includes rest from aggravating activity, ice, compression, elevation, and supportive footwear. In more painful cases, a walking boot and crutches may be used for a short period.
Activity Modification
One of the most important parts of treatment is reducing the type of activity that is continuing to irritate the tendon. That does not always mean complete rest, but it often means stepping back from running, jumping, hills, or other activities that put repeated stress on the Achilles until symptoms improve. Some patients switch temporarily to lower-impact exercise such as swimming or deep-water running.
Physical Therapy and Strengthening
Physical therapy is often a major part of recovery. Treatment may include exercises designed to heal and strengthen the Achilles tendon, with progressive loading as symptoms allow. Heel raises and other strengthening exercises are commonly used, especially for more persistent Achilles pain.
Orthotics, Heel Lifts, and Support
Some patients benefit from a shoe insert, heel wedge, or heel pad to reduce strain on the tendon and make walking more comfortable. Supportive shoes can also help reduce irritation during recovery.
Medication and Other Nonsurgical Options
Anti-inflammatory medication may help with pain relief, especially early on. In more stubborn cases, other options may be discussed before surgery, including therapies such as shock wave treatment.
When Surgery Is Considered for Achilles Tendonitis
Surgery is not needed for most patients with Achilles tendonitis. It is more often considered when symptoms have lasted for months, when the tendon is not improving with structured nonsurgical treatment, or when the tendon has torn or developed more significant damage. Mayo Clinic notes that surgery may be discussed if several months of conservative treatment have not worked, or if the tendon has torn.
Surgery may be discussed when:
• pain continues despite activity modification, therapy, and other nonsurgical treatment,
• the tendon remains too painful for walking, work, or exercise,
• symptoms keep returning with attempts to resume activity,
• or there is more significant tendon damage that is not improving.
The best way to know whether further treatment is needed is through an orthopedic evaluation that considers symptoms, exam findings, imaging when needed, and how the tendon has responded to rehabilitation.
