Guess I'm in trouble because I had three head injuries in a short period of time, including getting hit by a car, when I was a kid...don't really want to relive that one but I'll do whatever it takes to get better.
From a retracing standpoint, the only thing I've noticed is that in my dreams I've revisited some emotional events (such as the death of a grandparent) and felt better emotionally afterwards. But I think I'm a ways away from having physical relief or having a retracing as clearly physical as you describe above.
So helpful again that you're sharing your experience, many thanks.
