@Markus Burri Just started using ultrasound in the last few days with the US Pro 2000. Previously used Pulsetto. I found the Pulsetto beneficial, but inconsistent in results. First impressions of Ultrasound. Much stronger, much deeper, more potential. Touched immediately on some deeper trauma patterns I am aware of, which made it slightly uncomfortable, but very exciting. That's exactly where I want to go. Part of the immediate response was a very quick reduction in inflammatory patterns in the nervous system, especially in the head and sacrum. I find inflammation pushes me out of the physical pain, and more into a hazy indistinguishable type of fire pain. This vanished quickly, leaving just the underlying physical tightness and contraction. As said, this is where I want to be from experience. It always leads to deeper healing. The trick is to just enter into it without being overwhelmed emotional. The first night was uncomfortable as said, but there is context. My TBI pattern had triggered during the day, which always leads to an immediate inflammation cascade. After the ultrasound, I was just left with the underlying physical contraction. The normal emotional response was also gone. So whilst uncomfortable, I was quite happy to sit there and let the body do what it needed to do. Second night was much better, just waking for an hour in the night, and letting the body unwind. Another shift I noticed was doing some CST with my wife. We're both CST practitioners and do small sessions on ourselves daily. Normally my interioception from my left hand is much weaker and more clouded than my right hand. After the ultrasound, they were pretty similar. Much stronger and clearer feedback from the left hand, almost to the right hands levels. At the moment I'm just figuring out how much to do and what intensity. My drive wants faster and harder, but that's not what the body wants. Sterling's matrix chart is a pretty good guide for this as I learn how to use it best with my body.
