weird red spot (f24)

i cut myself with a box cutter at work monday and had to go and get stitches, this was my first time and they injected lidocaine to numb up the area, the wound looks fine however there's this odd red area under that's been there since i first took off the bandage to clean the stitches.. it doesn't hurt, itch, or anything really. it's the tiniest bit numb but other than that i don't know what's wrong and it's kinda stressing me out. am gonna post a picture of it in the comments
