I do a lot of that too. It is not easy to find always the connection.
For the longest time when I ate chips with hummus I got pain in the right breast. How weird is that. Sometimes I had it with other food too.
As long as I remember I often had pain in the front lower right, so I thought intestines, ovaries, appendix? One day I was flipping through Andreas book I saw a picture of reflex points in the bowel.
The gallbladder's reflex point was right low in front. I have a gallstone but my pain was never in the gallbladder area, but the pain was what I thought the intestines.
While I was looking at the drawing I noticed that above the gallbladder/hand/arm ribs was the right breast, all the sudden it made sense, my intestines were probably irretated by the food and I could feel it in the breast.
The only thing I wonder is the bowel first irretated and then I feel it in the breast or in my gallbladder case is it first the gallbladder and then the bowel.
More things to ponder.
