I get a stiff neck to, along with headaches and shoulder pain. At one point the pain in my neck was so bad my primary doctor ordered a cervical MRI. It came back negative of course. I continued with the anti-candida diet, starting taking Mg, and had all of my mercury fillings replaced (all 7). Also, following a gluten free diet helped to. Now that I am starting chelation and taking some stronger anti-fungals, I get the stiffness as die off.
I think taking magnesium is one of the easiest first things anyone could try.
