The injection to put the epidural anesthesia or the catheter with the anesthesia may be a little uncomfortable, but it does not hurt. Usually, the anesthesiologist puts some anesthetic first on the skin of the area so that the woman does not feel the introduction of the larger needle.
Some women may feel the needle stick more than others, but in principle the epidural anesthesia does not hurt. What is important is that the woman be completely still so that the anesthesiologist can make the puncture without any complications.
