MPS typically occurs after a muscle has been contracted repetitively. This can be caused by repetitive motions used in jobs or hobbies or by stress-related muscle tension (Myoclinic.org). Knowing the cause of trigger points pain will make it easier for you to manage your symptoms. I find the following advice from my rehab doc and from chronic pain resources I've found in the internet helpful:
1. As much as possible reduce stress in your life. Get rid if not remove toxic people in your life. If you find yourself getting angry or upset, take a deep breath and try to detach yourself emotionally from the situation. By the way, I have discovered or realized that being in pain for so long can make you more emotional and sensitive, well, at least in my experience. It seemed the tender points in my muscles have extended to my emotions..
2. Do deep breathing exercises. You can ask your PT or other health care provider to teach you or search trusted sources for this.
3. Listen to your body, learn how much can your body take and when to stop when doing chores and other activities and even when doing nothing
4. Take hot showers first thing in the morning when stiffness is worse.
5. Do gentle exercises regularly and hot compress.
6. Observe proper posture at all times and do not stay in same position for a long time
7. I get shockwave and laser treatment during my PT sessions
8. Eat healthy, spend time with supportive love ones and nature.
7. Make your bed and bedroom comfortable and soothing for you
8. Surround yourself with things that spark joy, and
9. Don't just rely on your doctors and PT to get better, be active in finding ways to get better
