Lipoma on one side but forehead ridge on the other? What can be done? (photo)

Over the past few years I have noticed what my doctor tells me is a lipoma on one side of my forehead. I have an appointment with a plastic surgeon to get this looked at in a few weeks as it is now becoming so obvious in photos that I'd rather have the scar. The thing is I've noticed a "ridge" in my forehead on the other side too. I'm not 100% sure it's always been there & it's now obvious I pics too. It's harder though, feels like bone. Could filler help disguise it? Or does it need shaving?
