Every day I, without warning, I get a pressure/spasm in my neck and feel a pressure behind my eyes and spend a couple of minutes in strong vertigo. My eyes get out of focus, like a cross eyed, and the world gets out of alignment and most times spins . For over 12 years, I went a chiropractor and got neck manipulations, that would work great. 2 years ago, had surgery for prostate cancer and after spending months recuperating from that, never went to a chiropractor again. Maybe I need to go back to a chiropractor.
