Before you buy a new saddle, I would suggest you make sure the fit is right otherwise. Sometimes just a bit up, down, forward or back, or a bit of tilt one way or another makes all the difference. I found some of those gel covers also helpful as well as the gel underwear, (or the gel version of cycling shorts) but saddle is personal. What works for one might not work for another.
If you still need a saddle, take your bike with you to your local bike shop. Let them check and see how you are sitting, and sometimes the old vet can spot or suggest something that immediately solves the problem. The right bike shop can steer you in some directions to think about for the type of riding you do.
One other thing I learned. If your body starts to hurt, listen its trying to tell you something. Find out why. In my case it was a knee, but its was just a little ache. I decided it was just soreness and pushed on. Well the result was later I found out the seat was too low and spent a month taking a medication to reduce the swelling an to help it heal. Injury was directly related to the fit of the bike. I was lucky. I didn't do enough damage to need an MRI ect, but I don't think I was far from it.
