New Saddle, does it need more time?

[XMcShiftersonX]

Well, after 1800 miles on my Fizik Vitesse Tri saddle (including 3 centuries!), I started to notice a lot of irritation at my labia and clitoris. So much so, that my last couple rides had been pretty uncomfortable and I (as well as my friend) noticed I was shifting around a lot on my saddle. I think it has always been somewhat of a problem, but I figured some discomfort was normal and I would just add more chamois cream. I never developed any sores, just irritation and some swelling.

So, I decided to try a new saddle. After reading suggestions on here for what people liked the most, visiting a LBS to have my butt measured and get their recommendations (and being told that all the pressure should be only on my sits bones, none should be on my labia), as well as talking to my husband who has the Specialized Toupe that he loves, I decided to get the Specialized Ruby.

Yesterday was my first test ride with it. My husband and I did a 55 miles ride with 2200 feet of climbing. As soon as I sat on the seat I could feel the difference and what the man at the LBS was talking about, how all the pressure is on your sits bones. I had absolutely no pressure on my labia for the entire ride, and no post ride soreness, which was amazing!

What I did notice, however, as time went on was soreness on the inside of my right sits bone. It was pretty bad sometimes, but as soon as I got off the bike it was fine. Today, I notice some soreness if I touch that same spot though. So, I'm wondering if there is some bruising, though there are no visible marks.

What could be my problem? Do I need to just put more chamois cream there? Should I give the saddle more time to break in? Is the saddle not the right size for me? Based on my measurements the guy told me either the 143 or 155 would be fine because I was right on the cusp, but he would probably go with the 143. I'm pretty petite.

I know there's been many discussions about this. And I've tried reading over the many there were but only found one that talked about inner hip pain, which seemed more like chaffing, and not like what I experienced.

Any input would be appreciated,
