Unfortunately not an easy solution. Everyone seems to get trigger points but we don't fully understand the causes. Pain's pretty complex, so some things might work in some cases but not others.

A shortlist of stuff that could help includes exercise, massage (self-massage too), stretching, heat, dry needling or acupuncture. A portion of how much a particular therapy might help can be attributed to your interaction with the practitioner and your personal beliefs around that therapy (see biopsychosocial model of pain). Stress relief, adequate sleep, and improving general health (physical and psychological) can also contribute.
