Achilles Tendonitis TreatmentIf you suffer from pain and have a tender swelling in the large tendon (Achilles tendon) which attaches on the back of your heel bone, (calcaneus), you most likely are suffering from Achilles tendinitis. The pain is generally worse in the morning or after you have done some exercise.
What Causes Achilles Tendonitis?The Achilles tendon is a thick band of collagen which attaches your calf muscles to your heel bone. These muscles cause your foot to point downwards and to propel you forward when you are walking or running. When you are walking, your foot at first pronates (the sole turns outwards) and the bones of your midfoot separate to accommodate to the irregularities of the ground (they become a loose bag of bones). As your leg moves forward your foot supinates, that is, the sole of your foot tends to turn inward. This causes the bones of your midfoot to lock together so that your foot becomes a rigid lever that your calf muscles can use to easily propel you forward. If your foot is overpronated, your foot will not supinate when your leg moves forward which means that your calf muscle, instead of having a rigid lever to work with has to strain to pull up your midfoot which is only a loose bag of bones at that point. This will overstrain not only your calf muscles but also your Achilles tendon. If you’re a heavy, older, do a lot of jumping or running or prolonged walking, you are more likely to injure your Achilles tendon. When this happens, the tendon will develop many small tears and your body will try to fix them with inflammation. This is what will cause the swelling and tenderness which you find in Achilles tendonitis.
Nerve InjuryThe nerves which supply the skin around the Achilles tendon, and also innervate the tendon, can, if injured, swell. The swelling traps them in the tiny holes through the fascia, the fibrous covering of the muscles through which they must pass to get to the skin. Once trapped, they cannot “slim down”, as they keep re-injuring themselves on the walls of these holes., and this swelling can cause constant, at times severe pain. It also causes the tendon to deteriorate, as these nerves function to make sure that every part of your body is in good shape. When they are injured, that part of your body will cease to function normally.
