Why does the wound itch when it rains on cloudy days?

When the weather changes suddenly, because the temperature difference between hot and cold and the dry and wet changes are much stronger than usual, the nerve endings in the scar can sensitively detect this change and tell the body with the signals of itching and pain.

With the passage of time, the proliferation of fibrous tissue gradually stopped, and the scar gradually became flat, soft and light brown or grayish white. This is when the scar enters the stage of degeneration and atrophy, and the symptoms of itching and pain will gradually reduce or disappear.

Matters needing attention

Scar hyperplasia will be red, purple and hard, protruding on the skin surface, and there will be an itchy feeling. Moreover, hyperplastic scars are very sensitive to the external environment. As long as the environment changes slightly, the scar will have obvious itching.
