I had an operation several months ago. I thought the scar was beginning to fade but now I am convinced it is getting darker (and has been for the past few days). It was a pinky-red, but now it is dark purple/brown/black in places. It looks like bruising/old blood, but it definitely wasn't there before.
Is it likely to be old bruising working its way up to the surface? Or is it more likely to be fresh damage to the scar tissue? Either way, I'm assuming it isn't anything to worry (much) about. Slightly disconcerting though.
