A very experienced osteopath once told his trainees - dont chase pain, fix their posture, muscles, range of motion. If their pain goes away, that's their problem.

I guess what I am trying to say is that, your trigger points are developing due to muscle imbalances. Now unless you have something serious going on like trauma (whiplash, fall, accident) or nerve issues (disc issues etc), chances are more likely or not, posture and movement challenges ingrained for a time may have cumulatively caused trigger points to develop.

So meditation + light PT or yoga may be all that you need to get better. Best of luck!!
