First of all, I am just a newly dx (2 years) guy trying to live the best life possible. It’s fairly common to have a head or neck injury shortly before being DX with PD.
Looking back, my symptoms started shortly after a head injury that damaged my neck. I was begged by a friend of mine to see this guy. A NUCCA chiropractor. Very little pushing/adjusting on you neck. He X-rays its to make sure. My anxiety left within minutes. It makes sense to me. Makes sense to the guy that invented the MRI Raymond damadian. He thought lots of brain problems could be caused by it?
