You really should go back to the fitter and get their input on this.
If, for whatever reason, you want to chase this down here, some profile pics of you on the bike at the bottom of the stroke, or even better, a video of you pedaling the bike on a stationary trainer, also taken from the side, would be the most efficient way to tackle the issue.
This is all good advice, couldn't add anything intelligent if I wanted to. But I am surprised you were riding with a saddle that was a full 2 inches too low. Was your saddle and bars the same height before, and now the saddle is 2 inches higher than the bars? For sure that could cause back and neck pain.
