The anesthetic is administered. The procedure does not begin until you are numb. There will be temporary, mild pain from the injection of local anesthetic. When the anesthetic takes effect, the surgeon inserts the biopsy needle into the liver. You may experience pain similar to a punch on the shoulder when the biopsy needle goes in.
