Had almost exactly the same problem, down to identical symptoms -- same side of my body, etc.
My guess it that it's due to some supplements I was taking years ago (chiefly 5-HTP and magnesium) causing chest pain and/or heart palpitations, and the experience of that etching trauma into my psyche in a way that makes me experience physical symptoms. The worst part is that it feeds on itself, until I was sitting on a sidewalk having a panic attack causing massive hyperventilation and crushing chest pain, certain I was having a heart attack, barely able to dial 911.
Unfortunately it took $8000 in hospital bills from multiple emergency room visits to figure this out.
