Achilles tendinitis is an inflammation (swelling) of the tendon, which usually occurs as a result of overuse injury. Basketball players are the most susceptible to Achilles tendinitis because of the frequent jumping. Any activity requiring a constant pushing off the foot, such as running or dancing, may result in swelling of the tendon.
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.
People with Achilles tendinitis may experience pain during and after exercising. Running and jumping activities become painful and difficult. Symptoms include stiffness and pain in the back of the ankle when pushing off the ball of the foot. For patients with chronic tendinitis (longer than six weeks), x-rays may reveal calcification (hardening of the tissue) in the tendon. Chronic tendinitis can result in a breakdown of the tendon, or tendinosis, which weakens the tendon and may cause a rupture.
A doctor examines the patient, checking for pain and swelling along the posterior of the leg. The doctor interviews the patient regarding the onset, history, and description of pain and weakness. The muscles, tissues, bones, and blood vessels may be evaluated with imaging studies, such as X-ray, ultrasound, or MRI.
Make sure that the tendon is not torn through and through. If it is severed, you must see a doctor immediately so that the tendon can be repaired. Severe injuries can sever a tendon, without a skin laceration being present. Testing involves moving the toes and foot to see if the tendon moves. If the tendon does not appear to move, it may be severed (comparing the injured tendon and its movement to the same tendon on the uninjured foot may help). Very sharp pain, a sudden pop, or an obvious gap in the structure of the tendon are all signs of a rupture, and should be seen by a doctor as soon as possible. If there is extreme swelling of the leg, and pain (out of proportion to the amount of trauma received), you may have sustained a vascular injury. A doctor must see this type of injury immediately. If you are not sure, see a doctor. If you have multiple injured areas see a doctor immediately, in order to prevent excessive swelling and pain. If the above exam is negative, then you may proceed with self-treatment. (However, if you are not sure of the extent of your injury, you should consult your doctor immediately). The sooner you begin to treat your injury by following “R.I.C.E.”, the better you will feel. Rest is very important. Take off your shoe, get off your feet, and relax. Ice should be applied as soon as possible. Never apply ice directly on the injured area, as the cold may make the pain worse. Ice should be applied close to the injured site, between the heart and the injury, so that as the blood flows under the ice, it will be cooled. This cool blood flowing into the injured area will help to reduce the swelling and pain. Apply the ice, wrapped in a cloth or over an elastic bandage, to the foot for 15 minutes, every 1-2 hours, for up to 3 days after an injury. If the ice is uncomfortable, or causes increased pain, do not continue to use it, and see a doctor. If you have poor circulation do not use ice, as this may cause a serious problem. c. Compression is used to limit swelling, and to give support to the injured area. Compression should be applied to the entire foot, starting first at the toes and working back to the ankle. If it is applied just to the injured area, increased swelling will occur in front and behind the wrapping. Compression should be applied with a 3-inch elastic bandage, beginning around the base of all the toes, and then going around the foot and ankle. Continue over the calf muscle when possible. Compression reduces motion in the injured area and foot, and this decreases the pain, and allows for quicker healing. The bandage should not be so tight that it causes increased pain or throbbing in the toes or foot. It should be comfortable! Do not remove the elastic bandage for the first 12 hours, unless it becomes too tight, or the pain increases, or the toes become pale, blue, or cool. If any of these things happen, immediately remove all bandages, and leave them off for several hours. The normal color and temperature of the toes should return immediately. If not, see a doctor immediately! Continue until the swelling and pain subsides; it could take from several days to several weeks. d. Elevation of the leg will aid in reducing swelling and pain. Blood rushes to an injured area to bring increased blood cells, that aid in healing. Gravity will also force blood to the injured area. Too many cells and too much fluid will apply pressure to the injured nerves and tissues, and cause increased pain and delayed healing. Keep your foot elevated so that it is at least parallel to the ground, or higher if it is comfortable. Do this for at least 48 hours, or until the throbbing subsides, when you lower the leg.
Your doctor may recommend surgery if, after around six months, other treatments haven?t worked and your symptoms are having an impact on your day-to-day life. Surgery involves removing damaged areas of your tendon and repairing them.
A 2014 study looked at the effect of using foot orthotics on the Achilles tendon. The researchers found that running with foot orthotics resulted in a significant decrease in Achilles tendon load compared to running without orthotics. This study indicates that foot orthoses may act to reduce the incidence of chronic Achilles tendon pathologies in runners by reducing stress on the Achilles tendon1. Orthotics seem to reduce load on the Achilles tendon by reducing excessive pronation,
