Ashlyn Blocker, the Girl Who Feels No Pain Jeff Riedel for The New York Times Ashlyn Blocker, who feels no pain, at home in Patterson, GA. The girl who feels no pain was in the kitchen, stirring ramen noodles, when the spoon slipped from her hand and dropped into the pot of boiling water. It was a school night; the TV was on in the living room, and her mother was folding clothes on the couch. Without thinking, Ashlyn Blocker reached her right hand in to retrieve the spoon, then took her hand out of the water and stood looking at it under the oven light. She walked a few steps to the sink and ran cold water over all her faded white scars, then called to her mother, "I just put my fingers in!" Her mother, Tara Blocker, dropped the clothes and rushed to her daughter's side. "Oh, my lord!" she said - after 13 years, that same old fear - and then she got some ice and gently pressed it against her daughter's hand, relieved that the burn wasn't worse. "I showed her how to get another utensil and fish the spoon out," Tara said with a weary laugh when she recounted the story to me two months later. "Another thing," she said, "she's starting to use flat irons for her hair, and those things get superhot." Tara was sitting on the couch in a T-shirt printed with the words "Camp Painless But Hopeful." Ashlyn was curled on the living-room carpet crocheting a purse from one of the skeins of yarn she keeps piled in her room. Her 10-year-old sister, Tristen, was in the leather recliner, asleep on top of their father, John Blocker, who stretched out there after work and was slowly falling asleep, too. The house smelled of the homemade macaroni and cheese they were going to have for dinner. A South Georgia rainstorm drummed the gutters, and lightning illuminated the batting cage and the pool in the backyard. Without lifting her eyes from the crochet hooks in her hands, Ashlyn spoke up to add one detail to her mother's story. "I was just thinking, What did I just do?" she said. Over six days with the Blockers, I watched Ashlyn behave like any 13-year-old girl, brushing her hair, dancing around and jumping on her bed. I also saw her run without regard for her body through the house as her parents pleaded with her to stop. And she played an intense game of air hockey with her sister, slamming the puck on the table as hard and fast as she could. When she made an egg sandwich on the skillet, she pressed her hands onto the bread as Tara had taught her, to make sure it was cool before she put it into her mouth. She can feel warmth and coolness, but not the more extreme temperatures that would cause anyone else to recoil in pain. Tara and John weren't completely comfortable leaving Ashlyn alone in the kitchen, but it was something they felt they had to do, a concession to her growing independence. They made a point of telling stories about how responsible she is, but every one came with a companion anecdote that was painful to hear. There was the time she burned the flesh off the palms of her hands when she was 2. John was using a pressure-washer in the driveway and left its motor running; in the moments that they took their eyes off her, Ashlyn walked over and put her hands on the muffler. When she lifted them up the skin was seared away. There was the one about the fire ants that swarmed her in the backyard, biting her over a hundred times while she looked at them and yelled: "Bugs! Bugs! There was the time she broke her ankle and ran around on it for two days before her parents realized something was wrong. They told these stories as casually as they talked about Tristen's softball games or their son Dereck's golf skills, but it was clear they were still struggling after all these years with how to keep Ashlyn safe. A couple of nights after telling me the story about putting her hand in the boiling water, Ashlyn sat in the kitchen, playing with the headband that held back her long brown hair. We had all been drawing on napkins and playing checkers and listening to Ashlyn and Tristen sing "Call Me Maybe," when all of a sudden Tara gasped and lifted the hair away from her daughter's ears. She was bleeding beneath it. The headband had been cutting into her skin entire time we were sitting there.
