Trigger points are small, palpable nodes in muscle that typically develop in the upper back and shoulders. These contracted knots could cause “referred pain,” also known as pain that is felt in an area other than where it’s being caused. Individuals with chronic musculoskeletal pain disorders generally have an increased risk of developing trigger points.
Trigger Points Causes
Muscle injury, repetitive strain, and exertion overload are common causes of trigger points.
Trigger Points Symptoms
Trigger points may cause pain, referred pain, increased muscle stiffness, decreased range-of-motion, tingling, numbness, burning sensations, or muscle weakness. These symptoms are dependent upon the amount of stress being put on an affected muscle.
