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!!
