delivered my son via c section 5 months ago, I’ve since developed gall stones but that’s not what I’m asking for advice about.

I keep getting this weird feeling in my upper abdomen like a spasm or muscle popping it’s in the centre of my chest just where your bra would go. I was thinking is it related to post part I’m and my body still readjusting? Iv had it for a few months now. Has anyone experienced something similar after birth? It happens when I do certain things. Mostly when sitting and bending. Any advice stories welcome.
