I assume you are riding a flat-bar bike. How are your brake levers oriented on the handlebars? Are your wrists cocked at an angle when you ride, or are they straight? The ignorance of people who assemble bikes in LBSs is such that they almost never check the angle of the pods from the factory, which is horizontal; they should be between 30 and 45 degrees angle.

How much weight are you placing on your hands when you ride? Are your elbows locked? If so, you have issues back at the seat.
