Achilles tendinitis is a common condition that causes pain along the back of the leg near the heel. The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, and jump. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendonitis, a condition associated with overuse and degeneration. Tendons become inflamed for a variety of reasons, and the action of pulling the muscle becomes irritating. If the normal, smooth gliding motion of the tendon is impaired, the tendon will become inflamed and movement will become painful. This is called tendonitis, meaning inflammation of the tendon. Achilles tendonitis is typically not related to a specific injury. The problem results from repetitive stress to the tendon. This often happens when we push our bodies to do too much, too soon, but other factors can make it more likely to develop tendinitis, including: a sudden increase in the amount or intensity of exercise activity, tight calf muscles, or a bone spur that has developed where the tendon attaches to the heel bone.
What causes pain in the Achilles tendon?
Some of the causes of Achilles tendonitis include, overuse injury - this occurs when the Achilles tendon is stressed until it develops small tears. Runners seem to be the most susceptible. People who play sports that involve jumping, such as basketball, are also at increased risk. Arthritis - Achilles tendonitis can be a part of generalised inflammatory arthritis, such as ankylosing spondylitis or psoriatic arthritis. In these conditions, both tendons can be affected. Foot problems - some people with flat feet or hyperpronated feet (feet that turn inward while walking) are prone to Achilles tendonitis. The flattened arch pulls on calf muscles and keeps the Achilles tendon under tight strain. This constant mechanical stress on the heel and tendon can cause inflammation, pain and swelling of the tendon. Being overweight can make the problem worse. Footwear - wearing shoes with minimal support while walking or running can increase the risk, as can wearing high heels. Overweight and obesity - being overweight places more strain on many parts of the body, including the Achilles tendon. Quinolone antibiotics - can in some instances be associated with inflammatory tenosynovitis and, if present, will often be bilateral (both Achilles), coming on soon after exposure to the drug.
The primary symptom of Achilles tendon inflammation is pain in the back of the heel, which initially increases when exercise is begun and often lessens as exercise continues. A complete tear of the Achilles tendon typically occurs with a sudden forceful change in direction when running or playing tennis and is often accompanied by a sensation of having been struck in the back of the ankle and calf with an object such as a baseball bat.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose an Achilles injury such as Achilles tendonitis. Occasionally, further investigations such as an Ultrasound, X-ray or MRI scan may be required to assist with diagnosis and assess the severity of the condition.
NSAIDs help decrease swelling and pain or fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions. Steroid injections. Steroids decrease pain and swelling. After you get this shot, you may feel like your Achilles tendon is healed. Do not return to your regular exercise until your caregiver says it is okay. You could make the tendinitis worse, or even tear the tendon. Surgery. If your tendinitis does not heal with other treatments, you may need surgery. Surgery may be done to repair a tear in the tendon, or to remove parts of the tendon. The most important way to manage Achilles tendinitis is to rest. Rest decreases swelling and keeps your tendinitis from getting worse. You may feel pain when you begin to run or exercise. The pain usually goes away as your muscles warm up, but it may come back. Your caregiver may tell you to stop your usual training or exercise activities. He may give you other exercises to do until your Achilles tendon heals. Ice decreases swelling and pain. Put ice in a plastic bag. Cover it with a towel. Put this on your Achilles tendon for 15 to 20 minutes, 3 to 4 times each day. Do this for 2 to 3 days or until the pain goes away. After 2 or 3 days, you may use heat to decrease pain and stiffness. Use a hot water bottle, heating pad, whirlpool, or warm compress. To make a compress, soak a clean washcloth in warm water. Wring out the extra water and put it on your Achilles tendon 15 to 20 minutes, 3 to 4 times each day. Stretching and making the muscles stronger may help decrease stress on your Achilles tendon. Physical therapists can teach you exercises and treatments to help your tendinitis heal faster. You may need to wear inserts in your shoes. You may need to wrap tape around your heel and back of the leg. You may need to wear a cast, brace, or support boot.
Surgery usually isn't needed to treat Achilles tendinopathy. But in rare cases, someone might consider surgery when rubbing between the tendon and the tissue covering the tendon (tendon sheath) causes the sheath to become thick and fibrous. Surgery can be done to remove the fibrous tissue and repair any small tendon tears. This may also help prevent an Achilles tendon rupture.
There are several things you can do to reduce the risk of Achilles tendinitis, warm up every time before you exercise or play a sport. Switch up your exercises. Slowly increase the length and intensity of your workouts. Keep your muscles active and stay in shape all year-round. When you see symptoms of Achilles tendinitis, stop whatever activity you are doing and rest.
