It depends on individual pain tolerance level. My sister went through C section and her kids are 11 months apart. Yes, the pain is there as her stitches was almost opening up. However, she endure it pretty well. She wear velcro wrap to carefully to keep posture straight and avoid hunching. She did her confinement pretty good too. She dont seat a lot and walk about when needed. So far so good through the confinement and massage.
Dont think much and be positive. As long as baby & you are safe that's good. Healing will take process but soon will get better.
