After completing a 200+ mile, 4 day trip along the C&O Canal, I started experiencing loud clicking and mild pain in my left knee. Seems to be coming from the side of my knee cap. I took nearly a week off of the bike to allow for some recovery but am back on it now for my daily commute (riding very gently). It's only slightly tender when I'm on the bike, however, walking can hurt. Ice and Ibuprofin don't seem to help much. I ride with SPD's too, can you confirm the toe-out orientation? I haven't heard of this. I'm slightly worried since this seems to be a chronic problem, lasting longer than other joint pain I've had in the past.
