Something like a black scab on the surgical line.. Please help.

It's been 2 months since the incision was made.. When I close my eyes, there are two very small black dots on the left, one on the right, on the surgery line. The month has passed and the rest of the parts are fine, but only three parts are black and it feels unsettling . After that, I think I read an article saying that when I removed the stitches at the Seongyesa Temple, it didn't work properly, so I pulled it out by hand.. How about your experiences? Even after 2 months, can there be one or two scabs left? I try to scrape it off by hand, but it doesn't budge. Could this be a seam? It's been 2 months now and I'm still very uncomfortable. Please let me know ~~ Please @@
