Tendinitis can occur as a result of prolonged, unilateral or abnormal muscular activity.
One can experience pain, particularly when the inflamed tendon moves. There may be swelling around the tendon and the attached area. Sometimes it "squeaks" when you press on the swollen area. It almost feels like pressing a bag of potatoes. The most common places to get tendonitis are in fingers, wrists, elbows, shoulders, the back of the knees and achilles tendons.
A Tendonitis is an acute response of tendon and muscle as a result of overload or friction. Many mistake tendonitis for an infection. This can be explained with the word inflammation often being used in connection with inflammatory pain. Once infected, a foreign bacteria attack the body. The body then must defend itself, and in some cases one has to use antibiotics to help restore it.
Inflammation, however, is a physiological response to an overload, which is completely natural. When a structure, f.e. tendon is overloaded, it is the body's natural defence mechanism to initiate the inflammatory process. During the first few weeks the area can become swollen, hot and painful. This is a repair phase and the body is dependent on the process of repairing the damage.
