I recently bought a used road bike. I just went for my first 10 mile ride two weeks ago without padded shorts (which I have now). Ever since then I have had pain on the inner part of my right sit bone only, I thought it would heal up already. It doesn't hurt when when I sit down on a wooden chair or sofa but if I were to used my index finger and pinpoint the area with a push I feel the full breath of the pain on the bone again. I bought the bike to get back into shape I am overweight at 200 pounds standing at 5 feet 0 Inches not sure if that's a factor. Any advice?
