hypertrophic scar

A scar that's bothersome and unsightly because it's raised above the skin and looks like a lump due to too much collagen being produced during the healing process of a wound. It feels itchy and sometimes painful, too. It may take several years for them to flatten and fade, but until then they're a real pain and you're going to spend a bit of money on silicone sheets and scar gel to remove them. On the bright side, at least it's not a keloid.
