I honestly do not remember if it's something new. The mark itself is sooty and symmetrical, and it's making me a little worried. The outlet itself looks fine. There doesn't seem to be any damage to it. But the shape of the mark on the wall has me concerned. I am afraid it could be a burn mark from a wiring issue inside the wall. I just need to know if this is a situation where I need to call an electrician to come take a look. I would appreciate any advice you have.
