Mostly happens when I eat... go figure.  I worked restoring my house and was looking up at the ceilings ad working on them and the trim and sheet rocking etc., for 5 weeks.  That was a few months back but this has started. My neck hurts on the right side in the back at the top of my spine and I have a headache on and off down low in the back of my head. I went to the doctor and he sent  me to a allergist? I never get a doctor that can figure out what is wrong with me no matter what it is.   I'm going to get the B complex like the Doc said here on this site.  It's nerve related I know it is but the thing with it coming on when I eat is stupid? Help...?
