Tendonitis is inflammation of a tendon – the strong, white, fibrous tissue connecting muscle to bone. Tendonitis can be associated with a calcium deposit, which can cause inflammation. It is one of the common causes of acute pain in the shoulder and can occur after an injury or as a result of repetitious movements. In rare cases, it may also result from a disease.
Causes of tendonitis not mentioned elsewhere:
Tendonitis usually causes one or more of the following symptoms:
Acute tendonitis often subsides within 10 to 14 days.
In cases of Achilles tendonitis, if the tendon becomes more painful with greater activity such as running or playing sports, there is a chance the tendon could rupture: if not taken care of, tendonitis can weaken tendons, making them more susceptible to a tear.
If the pain worsens or continues after home care for over 14 days, a doctor should be consulted.
Cortisone shots may reduce the pain and assist in recovery, but will not regrow damaged tissue. Some doctors have made the claim, now supported by evidence, that cortisone shots can in fact weaken the structures being treated, and do not recommend them in spite of the temporary relief they may offer. (Care must be taken when injecting cortisone near any ligament or tendon: they must not be injected into.)
While the use of anti-inflammatories may reduce the swelling and pain, they also may hinder permanent recovery. Inflammation is part of the process for normal tendon regrowth. The chronic use of anti-inflammatories should be approached with caution.
Natural agents that have been used in tendonitis include MSM orally for pain relief.
