ciocc_cat, From everything I've read there seems to be a middle ground. That an ill fitting saddle can aggrevate an existing condition looks to be the primary concern for the doctors experianced with cyclists, along with where one sits on the saddle..the nose is a no-no.

I would look for a second doctor's opinion, preferably one familiar with sports and cycling in particular. There are so many body benefits for the cyclist that to stop seems nonsense to me for something that can be worked around.
