I have been searching for answers on why I have such bad brain fog and memory issues for over a year now. The only thing outside of the persistent fog that remains constant is my painful neck. I have been to multiple doctors and have had blood tests, MRI, X-ray, etc. All coming back normal, besides low testosterone. Which I am being treated for with no relief in symptoms. My question is has anyone ever experienced this and found what the problem is? The doc (from well known clinic in Southern MN) who scanned my neck didn't think the two were related and my neck only showed straightening of the regular curvature. I have been tested for everything, can anyone get me in the right direction. Is it anxiety/depression?
