From my experience with deeper cuts, the sensations youre describing sound like healing process. While the upper skin might be healing quickly it takes longer for the tissues and nerve endings underneath to knit back together. It will stop after a while.
Sorry to hear its triggering to you, but could you maybe shed a positive light on it? It feels weird because your body is working on healing itself, and in a way thats taking care of you. Look after yourself when you can, i hope it starts to feel better soon for you. I still use bio oil on my old scars that were once serious cuts, it helps take the taughtness out.
