Had an intradermal nevus on my face shaved down last year. Now same area feels hard and painful to touch. Should I see doctor?

I had an intradermal nevus on my face shaved down last year. Now same area of my face feels hard and mildly painful to touch. However, the skin appears fine. There's no visible sign of change. What is going on? Is my mole returning? Should I see my dermatologist again? Is this something I should be worried about?
