A large, painful lump on a scar could be a keloid or an infected scar. A keloid is an overgrowth of scar tissue that extends beyond the original wound, sometimes forming one or more large lumps, and is accompanied by pain. If the scar area becomes red, swollen, hot, or the pain intensifies, it may be an infected scar.
Another possibility is inflammation or damage to the tissues surrounding the scar, such as muscles, tendons, or nerves, which can also cause pain. This pain is often related to activity at the scar site; for example, it may worsen after strenuous exercise of the muscles near the scar.
If a large lump on a scar rapidly enlarges, accompanied by severe pain, fever, redness, or swelling, or if abnormal discharge appears in the scar area, this could be a sign of infection or other serious conditions. In such cases, immediate medical attention is necessary to prevent the condition from worsening. Pain in scar tissue is not always caused by infection; it could also be due to inflammation of the scar tissue itself or damage to surrounding tissues. Therefore, self-diagnosis or treatment should not be attempted; instead, professional medical help should be sought.
[Prevention Tips:]
1. Keep the wound clean to prevent infection.
2. Avoid strenuous exercise or external pressure on the scarred area.
3. Regularly observe changes in the scar, and seek medical attention promptly if any abnormalities are found.
4. Maintain good personal hygiene habits to enhance your body's immunity.
