But usually, all the above ideas work. They all worked for me until they didn't. Mine finally became a nodule with a bleeding sore on top, like blood on the shorts pad kind of thing.

I had a thing maybe like Masi61, above. I got it by riding a saddle which was too narrow for years. My dermo also diagnosed it as a cyst, but IMO it was a perineal nodular induration. Now it's just a total mess, a skin ulcer which won't heal. I'm beginning to doubt it will ever go away and maybe my long riding days are over.
