She had 3 knee surgeries. Her doctor did feel comfortable doing another one since she was only 35-36 at the time so he referred her to the pain clinic. The put in a spinal cord stimulator. She's got a battery pack and cords with electric nodes on the other end that come from the pack up her spine. It sends electric shocks to the nerves that connect to her knee to trick her brain into focusing on that instead of the pain. They had never put on in someone that young and told her she wasn't going to be able to lift or swing a baseball bat or ride roller coasters again. Done everything but the coasters so far.
