What to do if a scar itches

Generally, a knife scar refers to a scar left by a cut or incision. Incision scar itching can be relieved by cold compress, gentle massage, daily care and avoiding irritation, applying medication, laser treatment, and other methods. A detailed explanation is as follows:

1. Cold compress

Apply a towel or gauze soaked in normal saline to the affected area. A cold compress can reduce the sensitivity of nerve endings by lowering the local temperature, thereby alleviating the sensation of itching.

2. Gentle massage

Gently massage the scar area to promote blood circulation. Apply some lotion or massage oil before massaging to reduce skin irritation caused by friction.

3. Daily care and avoiding irritation

Clean the scar area with clean water and keep it clean. Avoid scratching the scar with your hands as much as possible to prevent infection or worsening of symptoms. Also, avoid using coarse fabrics or brushes on the scar area to reduce irritation.

4. Applying medication

If there is itching accompanied by fluid exudation at the incision scar site, it may indicate infection or inflammation. Under a doctor's guidance, topical medications such as halometasone cream, mometasone furoate cream, or licorice root ointment may be used for treatment.

5. Laser treatment

For scars that have healed for many years but still cause itching, laser treatment can be an option. Laser therapy can destroy scar tissue and promote epidermal regeneration and collagen tissue renewal through photothermal effects, thus improving the appearance and function of the scar and relieving itching.

If the itching from the incision scar persists or worsens, it is recommended to seek timely medical attention and consult a professional doctor. The doctor will formulate a more detailed treatment plan based on specific circumstances to ensure proper management and recovery of the scar.
