My daughter is a swimmer and injuried herself on day at practice. They said she had Extensor Tendonitis. She was fine after treatment for about week or so and her foot started bothering her again. It took a bit they finally got an MRI done it found nothing. So they took her to an ortho that specializes in foot and ankle. He said after looking at her foot and talking to her he said she had either RSD or Neuritis and sent her to a pain specialist. The pain specialist is the one that said she had RSD. She had a nerve block this past Tuesday. She started having these symptoms beginning or so in October. We live near Houston Texas and she is in school near Charlotte North Carolina. But she does not have a car at school and has to depend on the trainer to get her to her doctor appointments. Any thoughts would be great Thanks.
