Hi K.--I had my son via C-section almost 1 year ago. I've noticed also that if he climbs on me or jumps on me, or if I lean into something with that area of my stomach, it is still tender and gets sore easily. It's also weird because I have a lot of numbness above the incision site, but not on the actual scar. But that area doesn't hurt all the time; I don't notice it unless something hits it. My dr. told me that it can take a very long time (if it ever happens) for the incision site to heal and feel fully normal again, but I would suggest that if you notice tenderness all the time, no matter what, and if it is bothersome, that you talk to your dr. about it. It is probably just part of the healing process! I've never had any other surgeries either; my husband has had several major surgeries, all of which were quite a few years ago, and sometimes he even still feels pain. So it's probably normal, but I would mention it to your dr. I hope this helps a little; if you find anything out from your dr., please let me know what he/she said so that I can track my recovery too!:)
