Achilles Tendonitis is caused by a traumatic event, which might also effect the gastroc-soleus group. Chronic overuse may contribute to changes in the tendon, leading to degeneration and thickening of the tendon. Many times, the tendon has already exhibited tightness, burning sensation, and even difficult walking before a total rupture occurs. Degeneration in a tendon involves wear and tear over time and weakens the tendon, which is like a rope with various strands and fibers. The strands are called collagen.
Some strands break, others become jumbled and result in vulnerability under stress.
Nodules can form with tendons called tendonosis which greatly weakened and susceptible to rupture. involves a total rupture of the tendon and is common amongst middle aged warriors who improperly stretch and place great strain on the susceptible tendon. Frequently, the tendon has already exhibited tightness, burning sensation, and even difficult walking before a total rupture occurs. It will probably tender to the touch. If a rupture occurs, a loud snapping noise may result with severe pain to the calf and an inability to raise up on the toes. Achilles rupture requires ice immediately, if possible.
