Im scheduled for October 19. Im scared. I kayak , bike, hike and just retired as well as closing on a house in 10 days. I tore a meniscus again after having stem cells injected 7 months ago. I see the scar pictures, hear the stories and like others Im scared. My husband runs marathons and hikes 14 ers. Yikes. He will leave me behind! Thanks for listening to my pity party. I gotta get brave.
