another idea is to go to a different lbs to have a fit. Now, there would be a caveat here, in that you need to go to a reputable one who would not consider it an opportunity to hard sell you things you don't need, but is willing to offer an opinion on your current fitting.

Some way of getting a second opinion on your current fitting might not hurt. It could be that bike store #1 hasn't fitted you properly, despite seeming like they knew what to do.
