What Is Achilles Tendinitis?
Achilles tendinitis, also spelled tendonitis, is an overuse injury commonly experienced by runners and athletes. Inflammation of the Achilles tendon from repeated stress can cause pain, swelling, and stiffness. Treatments include rest, self-care, physical therapy, and using orthotic devices like braces, supports, and shoe inserts.
Do I Have Achilles Tendonitis?
The Achilles tendon connects the calf muscles to the heel bone, running down the back of lower leg. The largest tendon in the body, it is used when walking, running, climbing stairs, or standing on your toes. Achilles tendonitis is acute inflammation of the Achilles tendon that occurs from repeated stress or overuse.
- Noninsertional Achilles tendinitis affects the middle part of the tendon that may break down over time, causing it to swell and thicken. Younger, active individuals are more prone to this type of tendinitis.
- Insertional Achilles tendinitis happens where the tendon attaches to the heel bone. Here, damaged tissues harden with time and form heel spurs. Though it can affect anyone, long distance runners and people with tight calf muscles are at risk.
Symptoms of Achilles Tendinitis
Achilles tendonitis can feel like a mild ache in the back of the lower leg and heel that worsens with physical activity. It may take several weeks for symptoms to fully show. If you have constant Achilles tendon pain or heel pain, stop any physical activities and see your doctor.
If left untreated, Achilles tendinitis can lead to a rupture that requires surgery. Though most cases do not result from sudden injury, a popping sensation in the back of your calf or heel could be an Achilles tendon rupture and requires immediate medical attention.
Achilles tendinitis symptoms include:
- Pain or stiffness in the morning
- Pain that worsens with activity or after exercise
- Warmth or tenderness around the heel
- Swelling around the heel and tendon
- Thickening of the tendon
- Back of heel pain when wearing shoes
- Reduced range of motion when flexing the foot or ankle
- Weakness in the lower leg
What Causes Achilles Tendinitis?
Any activity that puts repeated stress on the Achilles tendon can cause inflammation and pain. Achilles tendonitis often occurs following a sudden increase in intensity or duration of exercise.
- Participating in activities like running, sports, or dance
- Working a job that puts stress on your feet and ankles
- Having flat feet or overpronation that puts added stress on the tendon
- Exercising with tight calf muscles
- Wearing shoes that are worn out or lack support
- Having Haglund’s deformity, a bony growth on the heel that rubs against the tendon
Almost 1 in 4 athletes will develop an Achilles tendon injury in their lifetime, according to the Cleveland Clinic. Because the tendon weakens with age, Achilles tendonitis is also common in middle-aged individuals who only participate in sports on the weekends.
Achilles Tendinitis Treatments & Self-Care
To diagnose Achilles tendonitis, your doctor will ask about your symptoms, perform a physical exam, and may order x-rays to look for bone spurs.
Most cases can be treated using Achilles tendinitis self-care strategies and interventions like:
- R.I.C.E. method (Rest, Ice, Compression, and Elevation)
- Nonsteroidal anti-inflammatory drugs, or NSAIDs
- Wearing orthotic devices like heel lifts and shoe inserts for heel pain
- Physical therapy for Achilles tendon stretches
- Shockwave therapy that promotes tissue healing
If symptoms do not improve after six months of treatment, Achilles tendinitis surgery may be necessary to repair the tendon, and remove damaged tissues and bone spurs.
