I need to self sooth often. I have a routine now. When the pain comes, I start with self-soothing, followed by telling myself I am safe,- Havening touch is the method I prefer. Its easy and inconspicuous, so I can do it anywhere. It's simple but effective for me. Simply rub the palms of your hands together, slowly, pay attention to the way your palms feel against each other.
Havening touch helps me calm my nervous system, so I can investigate the pain psychologically. Self-soothing helps me stay out of the pain fear loop. If you google havening touch, you will find an explanation of why and how it works, pretty cool brain science.
I wanted to share that I also had the experience of my legs refusing to work while out on walks. I was shocked to learn that someone else had a similar experience.
Every time I went for a walk, with in 10 to 15 minutes, my quads, hips and groin tightened. It felt like I couldn't control my legs. The muscles just got tighter the more emotional I became and every time it progressed to a place where my legs felt like they were on fire. Horrible searing pain that left me in tears (which I would fight back in public, hate crying in front of people) and I would have to hobble to a place to sit down. The pain didn't stop when I sat down, just continued. I got stuck in the pain fear loop every time. It was awful, horribly painful and so embarrassing. I was very mean to myself when this would happen. Now I know that being mean to myself increases my pain.
When I started this program, I experienced that type of pain daily, multiple times a day. I was at the end of my rope. The solutions my doctor gave me were not acceptable. It was not acceptable to be 52 and crippled by pain. It was a very dark time for me.
I will never be able to understand your pain, or your experience, all I can do is relate. I have to say the way you described it was spot on for me.
If I'm honest, I still fear pain. If my inner thigh starts to tighten, I get anxious that the pain is returning, which makes it worse. Before this program I had no idea that was even possible. I learned to be with the pain instead of in the pain and I learned that when I allowed myself to really cry (ugly cry) pain decreases for me. I rarely cried before, usally held it. When I first started SEP- I cried every day. I had a lot to release.
Last thing I want to say.... I am so sorry for all the emotional pain you lived with in your childhood. I can't imagine the damage a narcissistic psychiatrist can do to a child

I gasped when I read that.
