Question:  clarifying if Brain Stem Constellation is at least two conflicts, one of Right and Left side of the brain or can it be two conflicts on one side of the brain? And if it is Right and Left side of the brain, then does that always include a dorsal vagal response?

Regarding a KCT Syndrome example...Over ten years ago I was in Regen. phase and experiencing muscle inflammation and pain mostly in lower back but also neck, shoulder, hips, and I now I believe could have had a stress-active KCT conflict that was exacerbating the process and causing more of everything and I slowly gained weight and got my to my highest weight ever over the next two years, yes partially eating habits but I don't think that was the only reason...
Brain Stem Constellation:  recently for me had a bought with an upper respiratory infection...what was interesting was that I have had chronic tinnitus it seems only in the Left ear (ringing, only noticeable when quiet but not too loud) and I believe that is connected to not being able to let go of something...with the infection a week into it, the Right ear felt blocked, ringing/whooshing and confirmed fluid in the ear...this whole infection and symptoms happened after another encounter with a family member having to "take in" in more comments, the same family member I think connected to the Left ear "can't let go" ringing...After a breakout session in class that week and Kora was leading a demonstration with me with Meta H inquiry and I had a realization, that night I did a meditation on the realization and then had an image appear of a gear rotating around to the left, and then after that I had a blocked feeling in the left ear as well as the right ear...seemingly connected then to a conflict of trying to take in and digest and to also take out, let go of something, which is what I have been actively working on since September, preparing to start talking to this family member about long-standing unresolved issues.

I also have a plethora of examples of physical issues and diagnosis with all of the therapy clients I work with, still trying to discern which layers they may be from, etc.
One example of a Brain Stem constellation is a client who has a pattern with and had a relapse with a BS conflict anxious, nervous, trying to deal with a change, trying to be prepared for taking in new chunks, then can't take it, can't cope and shuts down, develops severe constipation and has to see the doctor.  Generally bowel movements are not regular and is operating from a parasympathetic state too often which is the default mode and intensifies with increased stress, reminders of original SBS.
