Im a large rider (6'5" 220lbs) who's rather new to mountain bike riding. I was riding 3 + times a week, but after my last ride that area started to hurt really bad. It usually hurts for a day or so, but this time it has stayed painful since Monday (2/21/11). There is no chafing or irritation visible. the tissue and bone hurt. I've tried new saddles and the pants are no help at all. Is it time to see a doctor?
