Scar tissue can have various appearances depending on several factors such as the location of the scar, the type of injury, and the person’s age and skin type. Generally, scar tissue tends to be tighter and thicker than the surrounding skin. It may appear raised, sunken, lumpy, or flat and may be red, skin-colored, or darker than the surrounding skin. Scar tissue may also be painful, itchy, or cause limited movement if it forms a contracture scar. Keloid scars are a type of raised scar that can form on tissues after an injury. They often appear on the upper body, particularly the chest, shoulders, and earlobes. Keloids are larger than the original wound, have a thick or lumpy appearance, and rise high above the rest of the skin. Over time, scar tissue may change in appearance. Initially, the scarring may look minimal, but over 4-6 weeks, the scar may get bigger or become raised, firm, and thick. However, over the next 2-3 months, the scar may become smaller and blend in more with the surrounding skin. In some cases, scar tissue can cause inflammation, redness, itchiness, throbbing, sensitivity to the touch, and reduced range of motion. Scar tissue fibrosis, a mass of hardened protein strands laid down haphazardly by fibroblasts at the injury site, is often a factor in chronic musculoskeletal pain.
