3. Achilles tendonitis
Tendonitis typically occurs as a result of the overuse of a muscle, a joint or a group of muscles. The Achilles tendon stretches from the heel into the belly of the calf and so a case of calf pain could well be caused by tendinitis of the Achilles. This is something that athletes need to be wary of, as tendonitis in the Achilles can be a precursor to or a warning sign of actually rupturing the Achilles tendon.
A full rupture can potentially be career-ending for professional sportsmen and women and so it is pertinent that these people listen to their bodies. Sometimes this tendonitis pain eases with physical activity, only to return again when resting.
The returning pain is nearly always worse and full recovery is usually only possible following a decent period of rest. The likelihood of someone rupturing their Achilles tendon is almost doubled when they fail to warm up properly.
