The wound had healed, so why did it hurt again?

In life, we will inevitably encounter various bumps and bruises. Some wounds cause pain after healing, which bothers many people. So, the wound was healed, why does it hurt again? This article will demystify this for you and provide you with the correct approach to wound care.

Wound healing principles

1. Inflammatory response

When the body is injured, an inflammatory reaction occurs at the injured site. The inflammatory response is a self-protective mechanism that helps clear bacteria and necrotic tissue from wounds. The inflammatory response causes symptoms such as redness, swelling, warmth, and pain, which are normal during the wound-healing process.

2. Cell proliferation and repair

Based on the inflammatory response, the body initiates cell proliferation and repair processes. New cells will continue to grow to fill the injured tissue, allowing the wound to heal gradually. During this process, the nerve endings are also gradually repaired, which may cause pain.

3. Scar formation

When a wound heals, the body forms scar tissue. Scar tissue is more fragile than normal tissue and can sometimes cause pain when exposed to external stimuli. This pain usually lessens over time.

What is the cause of wound pain?

1. Infection

If symptoms such as pain, redness, swelling, and fever occur during the healing process of the wound, it may be caused by infection. Infections may be caused by bacteria, viruses, or other microorganisms. At this time, you should seek medical treatment as soon as possible to avoid worsening of the condition.

2. Nerve ending stimulation

During the wound-healing process, nerve endings are also gradually repaired. If the nerve endings are irritated, pain may result. This pain usually lessens over time.

3. Pressure or traction on scar tissue

If scar tissue is compressed or stretched by outside forces, it may cause pain. For example, wearing tight clothing or engaging in strenuous exercise may irritate scar tissue and cause pain.

Proper wound care :

1. Clean the wound and use functional wound dressings

Keeping wounds clean and hygienic is key to preventing infection. After a hand injury, the wound should be cleaned promptly and functional wound dressings applied to the wound can reduce microbial contamination in water and air and facilitate rapid wound healing.

2. Avoid irritation

Avoid using harsh medications or cosmetics on or touching the wound. At the same time, avoid excessive massage or hot compress on the wound to avoid irritating nerve endings or causing infection.

3. Wear loose clothing

Wearing loose clothing can reduce irritation to the wound. Try to avoid wearing tight clothing or jewelry that can compress or stretch scar tissue.

4. Carry out appropriate exercise

Proper exercise can help promote blood circulation and metabolism, help wound healing, and reduce the formation of scar tissue. However, avoid strenuous exercise or exercise that overstretches your body.

5. Seek medical attention promptly

If the wound develops symptoms such as abnormal pain, redness, swelling, and fever during the healing process, you should seek medical attention as soon as possible. Your doctor may prescribe antibiotic medications or other treatments to help relieve symptoms and speed healing.

Understanding the principles of wound healing and mastering the correct care methods are the keys to relieving wound pain. In daily life, we should pay attention to keeping clean and hygienic, avoiding irritation, wearing loose clothes, performing appropriate exercises, and seeking medical treatment on time.
