What are the symptoms of hypertrophic scars?

Generally, hypertrophic scars may present symptoms such as color changes, texture alterations, abnormal shape, itching and pain, and functional limitations. A detailed analysis is as follows:

1. Color Changes

In the early stages of a hypertrophic scar, increased blood vessels and congestion within the scar tissue typically cause the scar to appear redder than the surrounding normal skin. Over time, its color may gradually turn dark red or purplish-red.

2. Texture Alterations

Due to excessive proliferation and disordered arrangement of collagen fibers within the scar tissue, the texture of the scar is harder and thicker compared to normal skin, with a rougher feel.

3. Abnormal Shape

Hypertrophic scars often have irregular shapes and may appear raised, sunken, or wrinkled. This abnormal morphology not only affects aesthetics but may also impact function to some extent.

4. Itching and Pain

The distribution and sensitivity of nerve endings within the scar tissue may change, leading to symptoms of itching or pain, which can disturb the patient's daily life.

5. Functional Limitations

If a hypertrophic scar is located near a joint or on an area with frequent movement, it may restrict the joint's range of motion, resulting in functional limitations. For example, scarring may affect the ability to bend or straighten fingers, thereby reducing hand function.

It is recommended that proper wound care be promptly performed after skin injury to prevent infection and reduce the likelihood of scar formation. Additionally, friction, pressure, and other irritations to the scar tissue should be avoided as much as possible to prevent aggravating scar hypertrophy.
