I don't think the stitches came out;; Is it okay if I just leave it alone?

I think it's been about 10 years since I had my stitches removed;; I’m finally seeing it now;; There is something like a black dot above the surgical line; I'm trying to rub something, but I can't feel it well;; It’s like stitches;; I kept pressing and pulling and touching it with eyebrow plucking tweezers, saying I was going to pluck it out now; The redness and swelling only got worse;; Going to the hospital is also a hassle;; Almost all of my skin has healed... It's already been more than 15 days since the surgery and about 16 days;; If I just leave it alone, will something like inflammation occur? ;;I didn't even know this existed, so I put on makeup and washed my face a lot;; -_- I go to the hospital to get it done, but I get it done by myself at home;; Wouldn't it be the same? -0- Is it okay to leave it alone? Going to the hospital is so annoying;;
