No it’s not painful at all! Contraction is much more painful 😅 you will think this is nothing as compared to others after you have give birth, really. Some people do think it’s discomfort or feel weird when removing but it’s just that two seconds. Catheter is needed because you should not be getting off the bed and walking around after your delivery, be it c section or natural. Please rest and recover. I delivered via natural birth. The nurse removed it for me the next day. Don’t worry so much! It’s really okay.
