I'm not quite sure how to describe this I asked my therapist the first time it happened during EMDR but he said he doesn't for sure. We were processing a new memory and it led to memories of my dad and I started feeling this strange sensation in my stomach or core area kind of like an uncontrollable need to stretch. It has been getting worse and worse. Now at certain times throughout the day or when I have certain memories it's very strong and it's extending to my arms and sometimes legs like a full-body uncontrollable stretch but it always starts in my core. Has anybody experienced anything like this before? It is getting to the point where it's embarrassing if people see me doing this.
