RT Journal A1 Jutel A, McBain L T1 DO we really need to know? JF JAMA JO JAMA YR 2012 FD October 17 VO 308 IS 15 SP 1533 OP 1534 DO 10.1001/2012.jama.12266 UL http://dx.doi.org/10.1001/2012.jama.12266 AB My thumb was sore and swollen, and by morning, I couldn't flick open my toothpaste tube or press the disconnect button on my mobile phone, small tasks I realized, for the first time, I usually reserved for my nondominant thumb. Lynn was physician on duty at the after-hours service. She looked over the digit carefully, tested my strength, localized the pain, and looked up at me.
