CausesWhen you place a
large amount of stress on your Achilles tendon too quickly, it can
become inflamed from
tiny tears that occur during the activity. A
sudden increase in a repetitive activity that involves the Achilles
tendon can be to blame. A number of other factors can cause Achilles
tendinitis, including: Improper conditioning.
Achilles tendinitis is most common among athletes whose bodies aren''t
properly conditioned for their sport or activity. Inadequate
flexibility and strength of the calf muscles can contribute to overload
of the tendon. Frequent stops and starts during the activity, as well
as activities that require repeated jumping — for example, basketball
or tennis — also can increase your risk of Achilles tendinitis.Too much, too soon.
Achilles tendinitis resulting from overuse can occur when you begin a
new exercise regimen. If you''re just beginning a new exercise program,
be sure to stretch before and after exercising, and start slowly,
increasing your activity over time. If you''re a runner, excessive hill
running can contribute to Achilles tendinitis.Flattened arch.
Flattening of the arch of your foot (excessive pronation) can place you
at increased risk of developing Achilles tendinitis. This is because of
the extra stress placed on you Achilles tendon when walking. If you
have excessive pronation, be sure to wear shoes with appropriate
support to avoid further aggravating your Achilles tendon.Trauma or
infection. In some cases, inflammation of the Achilles tendon is due to trauma or infection near the tendon.
