What causes trigger points?
Many factors can cause trigger points, but generally muscle overuse or overloading is the primary cause. Any activity or posture that requires a long, sustained contraction of a muscle can create trigger points in that muscle. In addition any posture or body position that puts a muscle in a shortened position for an extended period of time can cause trigger points to form and/or worsen. Mental stress and emotional exhaustion contribute greatly to trigger point activation. Other causes include physical trauma, improper exercising, and work related overuse activities.
