keep everything as it should be ,bad idea to move things off centre.if you take off your pedal ,add a few washers to pedal thread ,, you should get about a centimetre adjustment on that,also adjust your cleats (are you wearing cleats).other than that what about putting double bartape on ,first one gel next one ordanery bartape.hope that's something to go on, not nice when your in pain .best of luck hope you find the cure.
