I try yoga and exercise to help my trigger points, it didn't help much, what else can I do?

Massage. Ice massage and deep tissue massage is often helpful. There are devices available online that allow a patient to administer the massage themselves if they don't have a family member available. If that doesn't help, injections can be helpful.
Plenty. Massage, chiropractic, acupuncture, trigger point injections by a doctor. Be mindful of posture, stress and other causes to keep them from coming back.
