Hello. It's been a year since CS, my belly has tightened up pretty quickly and everything seems fine. I haven't experienced any pain around the incision at all, I lead an active lifestyle but decided to start exercising to tone up some muscles. Yesterday was my first time doing exercises on my abs and felt pain in the muscles around the incision. It's been 24 hours now, the abs don't hurt anymore but there's pain below my belly button near the incision like cramps. The incision itself is okay. I don't know what to do. Is it possible to see a gynecologist right now? Have you had this before? Is it just from muscle damage after CS? I gave birth naturally
