I'm 78 & have had Parkenson's for at least the last 6 years. I have a pain in my neck which hurts when I turn it sideways & makes a popping like noise when I move it sideways. I have family history of arthritis & when I told my family Dr. about this he said that it was arthritis, My P.D. is fairly mild with some memory problems & hand tremors. This pain is also in the lower part of my neck also. Any idea what it is & what I can do to help it?
