Achilles, the great Greek hero of the Trojan War Migraine Care Review as described in Homer's Iliad, is conceived out of a love affair between a mortal and a nymph, Thetis. She wanted to make her son immortal to protect him from a prophecy that he would be killed in war and attempted to do this by dipping him in the River Styx by his left heel. As his left heel never was submerged, it was the only point on his body that could sustain a mortal wound, thus the saying "Achilles Heel" to mean major weakness or flaw that could be the downfall of a person.
While we're not concerned about personality flaws here, we are talking about a more literal interpretation of the Achilles Heel term, more specifically, the Achilles tendon. The Achilles tendon is vital to normal leg function, which is why the term "Achilles Heel" also perfectly pertains to Achilles tendon injuries as much as it does a personal weakness or flaw.
Achilles Tendonitis is shown by pain behind the heel, usually in the "watershed zone of the tendon," which is the portion of the tendon that attaches to the bone just a few inches above the heel. Unlike other foot and ankle conditions where pain is increased after activity, Achilles Tendonitis pain heightens during a period of inactivity. Pain associated with exercise is most acute when pushing off or jumping.
However, there are two major conditions of the Achilles tendon that significantly differ from one another as well as treatments for each: Achilles tendonitis and Achilles tendonosis. Achilles tendonitis is a condition of irritation and inflammation of the large tendon in the back of the ankle, but with Achilles tendonosis, there is no tissue evidence of inflammation, though examination of the exposed tendon will show that it has lost some of its healthy glisten and a microscopic analysis may reveal the presence of small tears that could contribute to a rupture under the right circumstances.https://freepdfreview.com/migraine-care-review/
