I had the exact same problem when my fitter raised my saddle. I didn't even make it half of my normal ride before I had to tilt my saddle forward because there was just too much soft tissue pain! That didn't really help because it put too much pressure on my hands and shoulders. I did make it through the ride, though.

When I got home that day, I took a sharpie and marked my seat post where she wanted it. Then I lowered it about half way back to where I'd originally had it. This gave me time to adjust. After about a month, I was able to bring it back up to where she'd put it and this time, I was pain free. I think my soft tissues and core muscles just needed time to condition and an interim saddle height helped me do that.
