Hi Seth,
It's good to see you writing on this site again...it seems it's been awhile!
About the back pain, I can fully relate to that. Years ago, when I made the decision of distancing myself from an abusive mother and dysfunctional family, I started experiencing awful back pain. Going to a doctor didn't reveal any reason.
After some really good therapy I noticed my back pain started to go away. I made that connection with the past.
Now when my back hurts, I know memories have been stirred up.
Thank you writing about this. So many people struggle with ailments that have psychological roots.
