Context: She also has n't had much sympathy for my choice to eliminate some more complex and high - risk procedures from my clinical repertoire ; when I first came to town there were fewer specialists in the nearby cities , and primary care doctors in general did more procedures than they do now . This spring Priscilla developed back trouble and this summer she fractured her ankle . She did n't do well physically or emotionally , ended up firing her back specialist and usually would double check with me everything her orthopedist told her about her ankle .

Question: why did she double check with him about everything ?
Options:
0. she thinks he has back trouble also
1. she trusted her specialist more than him
2. None of the above choices .
3. she was worried about her specialists errors
Answer: 3
