Bulging vein for 3 months after forehead incision - is this ever going away? (Photo)

I had a small forehead lipoma removed from the forehead beginning of June. The incision has healed great and there doesn't feel like any scar-tissue underneath. Under the healed incision, my forehead vein has been bulging. I'm assuming it's from the severed flow it used to have, will this be permanent though? It hasn't gone down or away despite my incision healing nicely without any firmness underneath. I'm just scared I traded one bump to create another bump. People keep commenting on it sadly
