A hospital in Minneapolis is reporting success using acupuncture in its emergency room to treat conditions ranging from car accident injuries to migraines to kidney stones. The hospital was the first in the U.S. to staff its ER with an acupuncturist two years ago. After tracking 182 patients, it reports that pain scores in those who received acupuncture alone dropped by the same amount as those who also received analgesic painkillers. “No matter what I’m treating them for, many patients report feeling calmer, more relaxed, less anxious,” said Adam Reinstein, the acupuncturist in the hospital’s ER.
