Fibromyalgia Trigger Points
Some of the most common symptoms of fibromyalgia include widespread muscle pain, fatigue, and multiple tender points. Tender points are specific places on the body that hurt when even the slightest pressure is put on them. These can be found on the neck, shoulders, back, hips, and legs.
Because putting pressure on a tender point can certainly "trigger" pain in someone with fibromyalgia, some people refer to these spots as "trigger points." However, there are differences between a tender point and a trigger point. The main difference is that trigger points can produce referred pain, which is when a person feels pain in a different part of the body than where the actual problem is.
The relationship between trigger points and tender points is not clear. While trigger points are more often associated with myofascial pain syndrome, people with fibromyalgia may have both tender points and trigger points. In fact, one study found active trigger points in 38 percent of people with fibromyalgia.
