Achilles tendinitis is when the tendon that connects the back of your leg to your heel becomes swollen and painful near the bottom of the foot. This tendon is called the Achilles tendon. It is used for walking, running, and jumping.
There are several factors that can contribute to achilles tendonitis. First, you should know that the biggest contributor to chronic achilles tendonitis is ignoring pain in your achilles tendon and running through the pain of early achilles tendonitis. If your achilles tendon is getting sore it is time to pay attention to it, immediately. Sudden increases in training can contribute to achilles tendonitis. Excessive hill running or a sudden addition of hills and speed work can also contribute to this problem. Two sole construction flaws can also aggravate achilles tendonitis. The first is a sole that is too stiff, especially at the ball of the foot. (In case you are having difficulty locating the “ball” of your foot, I mean the part where the toes join the foot and at which the foot bends) If this area is stiff than the “lever arm” of the foot is longer and the achilles tendon will be under increased tension and the calf muscles must work harder to lift the heel off the ground. The second contributing shoe design factor which may lead to continuing achilles tendon problem is excessive heel cushioning. Air filled heels, while supposedly are now more resistant to deformation and leaks are not good for a sore achilles tendon. The reason for this is quite simple. If you are wearing a shoe that is designed to give great heel shock absorption what frequently happens is that after heel contact, the heel continues to sink lower while the shoe is absorbing the shock. This further stretches the achilles tendon, at a time when the leg and body are moving forward over the foot. Change your shoes to one without this “feature”. Of course another major factor is excessive tightness of the posterior leg muscles, the calf muscles and the hamstrings may contribute to prolonged achilles tendonitis. Gentle calf stretching should be performed preventatively. During a bout of acute achilles tendonitis, however, overly exuberant stretching should not be performed.
Symptoms of Achilles Tendinitis include the following. Pain and stiffness along the Achilles tendon in the morning. Pain along the tendon or back of the heel that worsens with activity. Severe pain the day after exercising. Thickening of the tendon. Bone spur (insertional tendinitis). Swelling that is present all the time and gets worse throughout the day with activity. If you have an Achilles tendon rupture, you might feel a pop or snap, accompanied by a sharp pain behind your ankle. You are likely to have difficulty walking properly. If you have ruptured your Achilles tendon then surgery is likely to be the best treatment option.
During the physical exam, your doctor will gently press on the affected area to determine the location of pain, tenderness or swelling. He or she will also evaluate the flexibility, alignment, range of motion and reflexes of your foot and ankle. Your doctor may order one or more of the following tests to assess your condition, X-rays. While X-rays can’t visualize soft tissues such as tendons, they may help rule out other conditions that can cause similar symptoms. Ultrasound. This device uses sound waves to visualize soft tissues like tendons. Ultrasound can also produce real-time images of the Achilles tendon in motion. Magnetic resonance imaging (MRI). Using radio waves and a very strong magnet, MRI machines can produce very detailed images of the Achilles tendon.
Treatment approaches for Achilles tendonitis or tendonosis are selected on the basis of how long the injury has been present and the degree of damage to the tendon. In the early stage, when there is sudden (acute) inflammation, one or more of the following options may be recommended. Immobilization. Immobilization may involve the use of a cast or removable walking boot to reduce forces through the Achilles tendon and promote healing. Ice. To reduce swelling due to inflammation, apply a bag of ice over a thin towel to the affected area for 20 minutes of each waking hour. Do not put ice directly against the skin. Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be helpful in reducing the pain and inflammation in the early stage of the condition. Orthotics. For those with over-pronation or gait abnormalities, custom orthotic devices may be prescribed. Night splints. Night splints help to maintain a stretch in the Achilles tendon during sleep. Physical therapy. Physical therapy may include strengthening exercises, soft-tissue massage/mobilization, gait and running re-education, stretching, and ultrasound therapy.
Occasionally, conservative management of Achilles tendon conditions fails. This failure is more common in older male patients and those with longstanding symptoms, those who persist in full training despite symptoms or those who have uncorrected predisposing factors. In these cases, surgery may be indicated. It should be remembered, however, that the rehabilitation program, particularly for severe Achilles tendon injuries, is a slow, lengthy program. Surgery is only indicated when there is failure to progress in the rehabilitation program. Surgery should not be considered unless at least six months of appropriate conservative management has failed to lead to improvement.
Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
