See, I was inclined to think that this could be the cause of the problem too. Partly because the pain is only in one shoulder, but also because I've had twinges in my left shoulder since I switched from rucksack to courier bag. My bikes are all the same, the riding positions haven't changed, only the bag is different. So...what sort of bag are you using? :-)
