3 weeks pp c section

I had an emergency c section at 35 weeks. I have been taking it very easy.. I'm doing light house work, not bending over not lifting anything. but my abs feel sore and I'm worried I'm ruining my stomach further somehow or delaying the healing process bc getting up and down out of bed or the chair is difficult and also changing my babys diaper and clothes causes me to stand in such a way, it causes me to use my abs. my abs often feel tight or sore. my incision is fine, sometimes itchy.

is what I'm feeling just abs healing or ?
