Typically an overuse injury, Achilles tendinitis affects the connective tissue between the calf and the heel. When you walk, run or otherwise use your leg to push your body upward, the Achilles tendon is engaged. Using the tendon frequently and with high intensity often results in tendinitis — a swollen Achilles tendon that makes it difficult and sometimes painful to continue high-impact activities.
The majority of Achilles tendon injuries are due to overuse injuries. Other factors that lead to Achilles tendonitis are improper shoe selection, inadequate stretching prior to engaging in athletics, a short Achilles tendon, direct trauma (injury) to the tendon, training errors and heel bone deformity. There is significant evidence that people with feet that role in excessively (over-pronate) are at greater risk for developing Achilles tendinitis. The increased pronation puts additional stress on the tendon, therefore, placing it at greater risk for injury.
If you have Achilles tendinitis or Achilles enthesopathy, you are likely to experience the following symptoms. Pain. You may notice aching, burning, or tearing pains at the back of your heel or above the ankle. The pain can range from mild to very severe and disabling. It is most noticeable in the following circumstances. After resting. Many people report that pain increases when they first get out of bed in the morning or after sitting for a period of time. After exercise. Pain may increase if you exercise or stand for a period of time. A lump. In some cases, a tender lump can develop at the site of the injured tendon (tendinosis). Bone spurs. When the injury occurs at the point where the tendon attaches to the foot, a bone spur may develop on the heel.
If you think you might have Achilles tendonitis, check in with your doctor before it gets any worse. Your doc will ask about the activities you’ve been doing and will examine your leg, foot, ankle, and knee for range of motion. If your pain is more severe, the doctor may also make sure you haven’t ruptured (torn) your Achilles tendon. To check this, the doc might have you lie face down and bend your knee while he or she presses on your calf muscles to see if your foot flexes. Any flexing of the foot means the tendon is at least partly intact. It’s possible that the doctor might also order an X-ray or MRI scan of your foot and leg to check for fractures, partial tears of the tendon, or signs of a condition that might get worse. Foot and ankle pain also might be a sign of other overuse injuries that can cause foot and heel pain, like plantar fasciitis and Sever’s disease. If you also have any problems like these, they also need to be treated.
Supportive shoes and orthotics. Pain from insertional Achilles tendinitis is often helped by certain shoes, as well as orthotic devices. For example, shoes that are softer at the back of the heel can reduce irritation of the tendon. In addition, heel lifts can take some strain off the tendon. Heel lifts are also very helpful for patients with insertional tendinitis because they can move the heel away from the back of the shoe, where rubbing can occur. They also take some strain off the tendon. Like a heel lift, a silicone Achilles sleeve can reduce irritation from the back of a shoe. If your pain is severe, your doctor may recommend a walking boot for a short time. This gives the tendon a chance to rest before any therapy is begun. Extended use of a boot is discouraged, though, because it can weaken your calf muscle. Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged tendon tissue. ESWT has not shown consistent results and, therefore, is not commonly performed. ESWT is noninvasive-it does not require a surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.
If non-surgical approaches fail to restore the tendon to its normal condition, surgery may be necessary. The foot and ankle surgeon will select the best procedure to repair the tendon, based upon the extent of the injury, the patient?s age and activity level, and other factors.
To lower your risk of Achilles tendonitis, stretch your calf muscles. Stretching at the beginning of each day will improve your agility and make you less prone to injury. You should also try to stretch both before and after workouts. To stretch your Achilles, stand with a straight leg, and lean forward as you keep your heel on the ground. If this is painful, be sure to check with a doctor. It is always a good idea to talk to your doctor before starting a new exercise routine. Whenever you begin a new fitness regimen, it is a good idea to set incremental goals. Gradually intensifying your physical activity is less likely to cause injury. Limiting sudden movements that jolt the heels and calves also helps to reduce the risk of Achilles tendonitis. Try combining both high- and low-impact exercises in your workouts to reduce stress on the tendon. For example, playing basketball can be combined with swimming. It doesn?t matter if you?re walking, running, or just hanging out. To decrease pressure on your calves and Achilles tendon, it?s important to always wear the right shoes. That means choosing shoes with proper cushioning and arch support. If you?ve worn a pair of shoes for a long time, consider replacing them or using arch supports. Some women feel pain in the Achilles tendon when switching from high heels to flats. Daily wearing of high heels can both tighten and shorten the Achilles tendon. Wearing flats causes additional bending in the foot. This can be painful for the high-heel wearer who is not accustomed to the resulting flexion. One effective strategy is to reduce the heel size of shoes gradually. This allows the tendon to slowly stretch and increase its range of motion.
