Hi so a quick background on me, I have been practicing Baguazhang and Xingyiquan for 1.5 years about now. About 1 year in I started focusing on Zhan Zhuang since I noticed I was lacking the power my teacher had, because he only focused on mostly forms and applications.

I started out doing 30 minutes of standing in 8 different postures via my Yiquan teacher and then eventually progressed to 1 hour in 1 posture which then progressed to 2 hours in the standing posture. I, then started experiencing Zi Fa Gong the problem is since then it's been an ongoing issue and seems to be evolving too different states it helps my kung fu and does help me become healthier. However I feel like there's a road block in my body, another bit of background information about me is that I have pelvic floor syndrome a disease where my pelvic floor accidentally locked itself up and won't release.

Whenever I stand now and even outside of standing, I can initiate the spontaneous movement by opening something in the back of my nostrils ( it feels like the holes that open up inside your mouth to allow air to come in. My spine would physically move and I would feel a wave traveling down my spine and into my feet.

This wave if allowed to travel would loosen my body and muscles, I also noticed if I did anything wrong in my martial arts form or circle walking practice I noticed it would create more severe blockages than it would possibly in a regular person. I would have to fix it via zhan zhuang.

I also noticed that my shoulders are one of the area this wave is trying to release as it's chronically tight due to me having crowded teeth and my tongue being unable to relax fully to support my head.

My questions are :

A.) Does anyone have any idea of what's going on inside my body? Is the Qi trapped due to my structural annomalies?

B.) Is this due to my pelvic floor syndrome or my jaw structure?
  C.) If it's due to my jaw structure in some way would I need to fix this via surgery to continue? Thank you.

PS : I have also went to see a Chinese Medical Doctor who specialized in Qi healing and he said that there was a nerve block in my pelvic area which is likely causing the spontaneous movements but his advice to focus on the dantian while standing just worsened the issue.
