Some people just don't react the "expected" way with these things. Like Div, I have had experience with dissolvable stitches not dissolving - my body kind of encapsulates them like an allergic reaction or infection and isolates them - and then I either need to be cut open again to get them out, or they come out as a result of infection. But it a nit every time, so there must be different types... My mum texts similarly. Most other people I have spoken to first hand reckon I'm odd because they've nit had a drama, and thankfully I haven't had any real issues since c/s - but there were other surgeries where I just didn't dissolve them properly - especially at the knot sites (endodontic surgery was horrific for it!)

Hopefully now that the stitch is gone you'll heal more effectively
