Okay, so I'm pretty embarrassed to have to ask about this subject, but here goes....

At the beginning of March, I was having some bad chafing issues where my inner thighs met my saddle.  I went to a professional fitter as I suspected it was a fit or saddle issue -- we made some significant changes (dropped the seat post and moved the saddle forward) and it took care of the chafing.

Unfortunately, not long after, I noticed a tender bump down there -- I chalked it up to an ingrown hair.  I was able to drain it and keep up the bike training.  But then I noticed another (and another, and another) tender bump.  Most of them are like blood blisters with a ton of pressure, making sitting on them uncomfortable. 

I've "drained" them (in that I've squeezed until blood shoots out and the pressure is relieved), but it seems only to be a temporary fix, as they fill back up within a few days.  I use chamois cream (and recently started trying bag balm), good shorts (that are removed quickly after a ride....as I head for the shower, so it's not like I'm sitting around in my filth), and have had a professional fit, but am going back for a follow-up later in the week.  I'm hoping tweaking the fit and/or replacing the saddle will get to the root cause.

But my real question is: now that I've got saddle sores, how in the world do I get rid of them?  I've been using a topical Benzoyl Peroxide solution to try to dry them out....and I even took a full week off the bike.  Do I need a doctor to drain them?  What kind of doctor does that (GP, dermatologist, gynecologist??)?  I've got a knee injury, so biking and swimming is all I can do....and with this issue, swimming is about the only thing I can do comfortably.  Would like to get back in the saddle!

Any saddle sores prior to this fitting?

Maybe the obvious cause is the changes you made...

If you never had saddle sores prior you may want to reevaluate your position, again…
