Oh I know your agony.
I found that the best way to remedy it is to get back on the bike. It takes about two weeks of walking funny, then....you have what I call biker's butt. No more agony. I find that if I ride year around, inside and out, then I don't have to go through the agony for two weeks. I have tried lots of different seats, including gels....it is like walking barefoot when you are a kid. Just get those feet tough....butt too.
Good luck
