My body shaking coincides with my pulse, its like my own heartbeat/pulse is moving my whole body, its very subtle but i notice it does it when i am still. I believe that my own heartbeat is moving my whole body. I heard from other sources that it could be if you are a skinny person, where you have no fat to absorb the "vibrations of the heart, so it just reverberates your body and making it move.
When i am still sometimes, my i get the sensation my body is like on a very shaky boat. side to side.

How is it possible that NOBODY has made it their passion to develop a cure PN???

PN as you know from this forum alone have more multiple causes, and majority of pn have unknown cause, even the ones that are known to cause it, has unknown triggers, and mechanism of actions. Its like asking the cure to cancer, which nobody is close to finding , because there so many different kinds like PN.
