I have a sharp , needle-jabbing like pain at the site of benign mole removal a year later.

The mole was in my upper back just to the right of my spine. It was a punch biopsy and I can feel the indentation in the skin but other than being a lighter pigment, it's not concerning by appearance. However, it feel sharp pain throughout the day as if needles ar being stuck in me at the site where the mole was. Usually it's when I'm moving my arms or back. Is this of concern or normal?
