Can microneedling cause pain in a scar treated with microneedling 8 weeks after the procedure? (Pohto)

I have a 3 year-old trauma scar above my upper lip (see photo). I grew facial hair so you can see the hairless, indented scar. Scar is wide/poor tone/texture. Eight weeks ago, I had my first micro needling with PRP. Don't see any improvement, but am experiencing stabbing/burning/tightening pain 8 weeks out. Scar was painful before micro needling, but not this painful. Can micro needling cause pain this long after treatment? Should I stop treatment? Should I be seeing improvement? Looks worse.
