I definitely meant taller bars in conjunction with a more-suitaable seat.Looking at the OP's current seat compared to a stocker and reading what he said about how it positions him it seems very unlikely that risers alone would alleviate much if any of his hip discomfort.
Risers would probably offer some relief for the Quasimodo effect but not for the hips etc. Being able to lift feet off the pegs and put them down on the ground at a stop probably supersedes a backache. Risers before a new seat option would probably mitigate a problem that doesn't yet exist. Even if it did it still seem secondary but risers remain a worthy recommendation.
You have to first position your butt to suit your lower half, then position your hands to suit your upper half.
