Having staples removed should not be very painful. Most people only experience slight discomfort, and many compare it to the feeling of a light pinch; some people report feeling nothing at all. If a staple becomes crooked in the skin, it can be more painful to remove.
Getting staples removed usually takes between one to five minutes, depending on the length of the wound and the number of staples involved. Staples are removed with a special remover that opens the staple fully before it is pulled out of the incision, which is why the skin is not damaged by the removal.
