Post-Mole Removal - Brownish again where mole used to be: A new mole or scarring? (Photos)

I had a mole removed early August and you can see the progression. August 9th a dark area appears to the south of the ex-mole area. August 25th and this south area is brown and is slightly elevated and it's as if the brown legion continues along a small elevated ring [the rest of the ring healing into skin color] (Keloid?) at the edge of the scar oval that is now left. Is this a new mole or scarring? Maybe sunburn? Or perhaps something else? What should I do? Please help! Thank you!
