I'm hoping someone can clear up a mystery for me.  I have vastly changed my way of eating and now eat very little dairy or wheat.  I haven't given them up completely and on occasion I will eat more of them than normal.  I then get a blocked feeling between my shoulder blades - it's very odd and uncomfortable.  It's not painful at all and doesn't take long to pass.  I sometimes get it when I eat a banana too. My body obviously isn't happy with what I've just eaten, but can someone explain to me why this happens - why my back and not my front?

Thanks

Sue
