What can result from excessive stress on a tendon?

Excessive stress on a tendon can lead to a strain, which occurs when the tendon or muscle is stretched beyond its normal limits. Strains are characterized by the tearing of fibers in the muscle or tendon, resulting in pain, swelling, bruising, and limited movement. Tendons connect muscles to bones, and when they experience excessive force—whether from overuse, a sudden movement, or lifting something too heavy—the fibers can become damaged.

In contrast, a sprain pertains specifically to ligaments, which are the connective tissues linking bones at joints, and typically results from a twist or blow to a joint. A fracture involves a break in a bone and is usually a consequence of extreme force or impact, not directly related to tendon stress. A seizure is a neurological event, unrelated to the physical stress on tendons or ligaments. Understanding these distinctions clarifies why a strain is the appropriate outcome of excessive stress on a tendon.
