For the past three weeks I have had to take my #2 bike because it's always threatening rain and I do not want to get my #1 bike wet. I developed a saddle sore on the right side. I deal with it by mixing a little OTC antibacterial cream with 1% cortisone cream. but first "before I ride" I wash the saddle sore with soap and water. Yes, "before". It works.
I pick my best shorts with the best chamois even if I have to hand wash them. Another trick I learned many years ago was to have more than one seat for my bikes. If you switch them the pressure points will change. Happy cycling.
