This trial is part of a larger, longitudinal study of symptoms that occur in the breast
surgical scar area and/or ipsilateral arm following breast cancer surgery. Women who develop
pain in the breast scar area or ipsilateral arm will be randomized to a placebo patch or a
lidocaine patch that they will wear on a daily basis for 12 weeks. We hypothesize that women
who wear the lidocaine patch will report a decrease in pain and decreased interference with
function compared to women who wear the placebo patch.
