Saddle sores @ narrow chami - pls help!

Another vote for the progetto X2 pad.  I picked up some Castelli Body Paints half price a few years ago, and I've stuck with Castelli ever since.  Not had problems even on all day rides, and never used cream.

You can get trial saddles in some places which you can take out for a ride, so that might save a costly mistake.  (Although we finished up buying the test saddle for my wife!)  

Difficulty you've got is that you've now got scar tissue and inflammation down there. How long are you riding for? It might be better to go out for shorter more intense rides until everything is healed. Are you shaving that area? It might actually be impacted hair follicles causing localised soreness. You're more likely to get those if you shave or trim.

You say that you're leaning forward a little more so you have in fact changed position - small changes make a huge difference to weight distribution around contact points and pedalling dynamics. Personal experience of this - intense lower back pain solved by a bike fitter (surprisingly to me) lengthening my stem by 10mm. Completely counter-intuitive but it meant that I was bearing more weight on my hands and my lower back muscles were under less strain.

I think the key here is to get healed up and then make one change at a time and see how it goes. Build your distance/time on the bike slowly - the aim should be to come home with no inflammation or soreness.

Saddles don't need to be painful, and you don't need a chamois to ride comfortably as long as you get the right saddle and aren't doing pro mileage. I now ride a Brooks B17 in padless mountain bike shorts with zero issues, even after an extended time off the bike. 

Ditch the bum cream I'd say. Never used it personally, never felt the need, never had a particularly bad saddle sore. I would think it's better have nothing slippery there to encourage movement between skin/shorts, rough fabric stays rough even when greasy 

I'd definitely try lowering the saddle a touch and if you still have problems (and the money) go for a bike fit. They say a good bike fit (possibly with a recommended saddle) removes the need for chamoix cream also

Only you'll find the answer to this, and there's a host of good answers here already, however in my experience things to check:

1) Old bib shorts lose their chamios comfort after a while, the most comfy shorts can cause the worst pain, once they've gone they've gone.

2) Correct sized bib shorts, I've learned the hard way that if you're inbetween sizes, size down on bib shorts, a chamois too big is a nightmare, a chamois which can move about can also be horrid. 

3) Bit personal, but longer hair can cause chaffing, mitigated with chamios cream obvs, but you could try getting the clippers out. 

4) Pilates.. joints and things can be more or less flexible, e.g. you can have longer or shorter limbs to a surprising degree. Pilates can help with this, I'm sure other things can too, but I've recently been on a talk and learned a lot about our bodies imbalances and things we can do to mitigate or change things.. (possibly off topic) including leg length, how most people don't actually have one limb shorter than the other contary to popular belief, it's more a skeletal positioning thing which can be changed with some focussed exercise. 

What Rutland said.

I dropped my saddle an 1/8th of an inch after getting same as you are experiencing.

I couldn't understand after all the years I'd be riding why it started to happen.Then after Doctors visit for annual MOT I discovered I'd lost height.Did my bike set up,used Assos cream (excellent by the way) and hey presto job's a good un.

Other thing buy some good shorts and don't skimp as they are worth it.Castelli progetto x2 and Endura's pads in right size for you are worth getting.I'm sure others will have their own favourite pad.

Saddle sores are often caused by the pelvis not being stable on the saddle - hence the rubbing - and the most likely cause of pelvic instability is the saddle being too high.  So, try lowering your saddle - it may feel a little strange to start with, but give it a chance...and it's free.
