How high are your bars? What was changed in your fitting and did the fitter say that you COULD do other things but you didn't have to? When I got my fitting the fitter liked most things about how I was setup when I went in. We did move my bars just a little and my saddle position...he did add that IF I was getting hand pain I could raise my bars a bit more but if I felt good it was fine. I since have ridden some bikes with higher bars and it really does take the pressure off. If you have too much drop for your fitness level (specifically core strength) you will get the back and neck pain and the weight on your hands will get you the numbness. You’re basically not supported properly and are putting too much on your arms.
