This is a strange one so bear with me. I get intense pain from my stomach up to my neck and left shoulder whenever I eat cereal with Spelt (a form of wheat). I read that there is a phrenic nerve running from from the diaphragm to each shoulder, so I think this is where the pain is. How can a spelt intolerance hurt in the phrenic nerve? All you Celiacs, does it ever hurt up to your neck if you eat wheat?
