How do trigger points differ from tender points?

Trigger points and tender points are both conditions related to muscle and soft tissue pain, but they have distinct characteristics. The primary differentiating factor is that trigger points are known for their ability to exhibit referred pain, meaning that when pressure is applied to a trigger point, it can cause pain to be felt in another part of the body, away from the original site of the trigger point. This referred pain can significantly impact a patient's experience of pain and discomfort.

On the other hand, tender points do not typically cause pain to be felt in other areas when activated. They are localized spots of tenderness found in muscles and are commonly associated with conditions such as fibromyalgia. While both types of points can be sensitive to touch, the defining feature of trigger points is their involvement in the broader phenomenon of referred pain, making the distinction between them important in clinical practice.

This understanding helps practitioners tailor treatment approaches, such as acupuncture or manual therapy, to effectively address the specific issues presented by each type of point.
