Causes
By Mayo Clinic staffAlthough tendinitis can be caused by a sudden injury, the condition is much more likely to stem from the repetition of a particular movement over time. Most people develop tendinitis because their jobs or hobbies involve repetitive motions, which put stress on the tendons needed to perform the tasks. Using proper technique is especially important when performing repetitive sports movements or job-related activities. Improper technique can overload the tendon — which can occur, for instance, with tennis elbow — and lead to tendinitis.
