I think there is a difference between a body memory and a physical ailment, although sometimes they overlap.

The most common body memories I have are of sexual things... I'll be some place or with someone and I get the sensation of being abused sexually. (It took me years to realize that this what was going on, it was hard to even admit I was having sensations in "those" places, etc)

As I began to understand triggers I realized these sensations were more likely to arise if I was feeling uncomfortable socially, or vulnerable, or threatened in some way.

On the other hand, I had chronic tummy aches as a kid... always in the nurse's office at school, etc. I think that those were just an ongoing effect of abuse... living in constant fear and hypervigilance... it's bound to have an impact on the body.

I think constant stress could lead to reflux, which would lead to medical problems like you describe.

Hope this makes sense. M
