Welcome to the forum!
I would suggest to let the body speak to you and tell you what's going on. There are probably different ways to do that....maybe with a therapist, a coach, a massage therapist....etc. Maybe a few Voice Dialogue sessions could help get to the bottom of it. Your body is trying to tell you something, for sure!!
The key to life is in being fully engaged and peacefully detached simultaneously and authentically in each moment.
