Achilles tendonitis is an inflammation of the Achilles tendon. This inflammation is typically short-lived. Over time, if not resolved, the condition may progress to a degeneration of the tendon (Achilles tendonosis), in which the tendon loses its organized structure and is likely to develop microscopic tears. Sometimes the degeneration involves the site where the Achilles tendon attaches to the heel bone. In rare cases, chronic degeneration with or without pain may result in rupture of the tendon.
Tight or fatigued calf muscles, which transfer the burden of running to the Achilles. This can be due to poor stretching, rapidly increasing distance, or over-training excessive hill running or speed work, both of which stress the Achilles more than other types of running. Inflexible running shoes, which, in some cases, may force the Achilles to twist. Runners who overpronate (feet rotate too far inward on impact) are most susceptible to Achilles tendinitis.
There will be a gradual onset of achilles tendon pain over a period of weeks, or even months. The pain will come on during exercise and is constant throughout the training session. Pain will be felt in the achilles tendon when walking especially up hill or up stairs. This is because the achilles is having to stretch further than normal. There is likely to be stiffness in the Achilles tendon especially in the morning or after a long period of rest. This is thought to be due to adhesions between the tendon sheath and the tendon itself. Nodules or lumps may be found in the achilles tendon, particularly 2-4cm above the heel and the skin will appear red. Pain and tenderness will be felt when pressing in on the achilles tendon which is likely to appear thickened or swollen. A creaking sensation may be felt when press the fingers into the sides of the tendon and moving the ankle.This is known as crepitus.
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.
Take a course (5 - 7 days) of non-steroidal anti-inflammatory drugs(ibuprofen/voltaren/cataflam/mobic) available from your general practitioner or pharmacist. Apply ice to the Achilles - for 10 minutes every 2 hours, in order to reduce the inflammation. Avoid weight-bearing activities and keep foot elevated where possible. Self-massage - using arnica oil or anti-inflammatory gel. Rub in semi-circles in all directions away from the knotted tissue, three times a day once the nodule is gone, stretch the calf muscle gently do not start running until you can do heel raises and jumping exercises without pain return to running gradually full recovery is usually between six to eight weeks.
Around 1 in 4 people who have persisting pain due to Achilles tendinopathy has surgery to treat the condition. Most people have a good result from surgery and their pain is relieved. Surgery involves either of the following, removing nodules or adhesions (parts of the fibres of the tendon that have stuck together) that have developed within the damaged tendon. Making a lengthways cut in the tendon to help to stimulate and encourage tendon healing. Complications from surgery are not common but, if they do occur, can include problems with wound healing.
Suggestions to reduce your risk of Achilles tendonitis include, incorporate stretching into your warm-up and cool-down routines, maintain an adequate level of fitness for your sport, avoid dramatic increases in sports training, if you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse, wear good quality supportive shoes appropriate to your sport. If there is foot deformity or flattening, obtain orthoses, avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury, maintain a normal healthy weight.
