What it is
Thickened scars and keloids form when the skin makes too much scar tissue as a wound heals. A thickened scar stays within the original wound, while a keloid grows beyond it. The scars can itch, feel tight and hurt. A doctor injects an anti-inflammatory medicine directly into the scar. It calms the scar tissue, so the scar becomes flatter and softer and the symptoms ease.
