Each tendon in your body has a protective sheath that helps the tendon stay lubricated (with synovial fluid) and glide smoothly between other soft tissue in the area. Injury to this 'sheath' means production of this synovial fluid is compromised or the fluid leaks outside the sheath. Either way, sheath damage often results in inadequate tendon lubrication. If you are suffering from an injury of this type to the Achilles tendon, the term is known as Tenosynovitis (or paratenonitis / peritendinitis). This basically means inflammation and degeneration of the tendon's outer layer or sheath.
It is possible to suffer from Achilles tenosynovitis alone but usually it occurs alongside achilles tendinosis - a chronic degeneration of the achilles tendon. In cases of tendonosis, the tendon swells up so much that it often tears the sheath. As your body tries to heal the tendon sheath, scar tissue forms inside the sheath - creating attachments from the tendon to the paratenon (paratenon=sheath). This scar tissue limits the gliding movement of the tendon in the sheath, reducing range of motion and causing sharp pains, tenderness, redness and swelling.
The pain you feel when you are suffering from Achilles paratenonitis (tenosynovitis) is usually a result of the inflammation in the tendon as well as the scar tissue that has built up between the tendon and the paratenon. When you move your Achilles tendon the scar tissue stops the tendon from gliding smoothly through the shealth. As the tendon moves, more tearing of the tissue occurs and more scar tissue begins to form as these tears heal. It's a cycle that needs to be broken by getting rid of the scar tissue. With Achilles tenosynovitis you may also experience:
In most instances, Achilles paratenonitis it is a result of repetitive strain or over-use that occurs over a period of time. It is common among runners and triathletes and is usually caused by improper training or weak tissue, such as:
