It sounds like you have pinched a nerve or two. That is NOT normal. I don't necessarily think a doctor will be able to help since the damage has been done, but I would not ride another mile on that saddle, as temporary damage can become chronic over time.

Unfortunately, I have no idea what to suggest re. another saddle, but obviously the one you have is not working for you. Have you had a bike fit?

Good luck -- hope you'll get the feeling back soon! The only place I've ever had numbness after riding was in my two smallest fingers on my left hand, and the feeling did come back before too long (and never recurred, interestingly).
