Boston, April 6, 2014 -- Lil' Stinker licks Lynn Crisci's face, after Crisci began to cry. Lil' Stinker is Crisci's service dog, and has been with Crisci since the first accident that left her with a brain injury and chronic pain. Crisci also lives with EDS, a connective tissue disorder, as well as another brain injury, PTSD, and more chronic pain from last year's marathon. Crisci plans to participate in the Marathon for the first time this year. Photograph by Carolyn Bick/BU News Service 2014.
