Hi i had my lumpectomy and axilary node clearence last friday and the drain was removed a week post op - i have a seroma building up in my underarm which they are going to aspirate on thursday - it is gernally numb under here, but just wondering if this will hurt still or not? Has anyone had any experience? I am hoping because it is numb mainly under my arm still that i wont be abe to feel the needle when they go to aspirate. Heres hoping anyways!
