The place where the operation is performed will itch on rainy days. Why?

Our body is a whole system, and the injured parts will heal automatically, but this healing is not completely restored. Just like a wall, it has a hole, and no matter how clever it is, it can't be repaired to the original extent.

After the fracture of our arm, thigh or other parts, even if it heals on cloudy days or before it rains, there will be signs. Because his injured part will be traditional in advance, this is because we fell, and its healing in this place has formed a special environment. It doesn't have normal blood pressure and oxygen changes like our original whole body system. When it rains on cloudy days, its nerves will become more sensitive because it is new. Our original body parts and bones may have been with us for decades, and then they were broken and rebuilt.

Simply put, it is because our bodies can be mended. Although they can still be restored, they will not affect our normal life too much at first, but the mended places are always different from new clothes. So is our body.

At ordinary times, physical exercise can be properly strengthened, because physical exercise can enhance the blood circulation speed of our body, reduce the nervousness of the injured part, reduce the appearance of scar blood vessels, or let him gradually return to normal. Massage can also be done properly, which can promote the normal walking of blood and reduce the appearance of knotted blood. When it rains today, this feeling of pain will be much less.

Of course, the most important thing is to keep warm when the weather changes frequently. Wear a little thicker, the temperature change that the body feels will be less obvious, and the feeling of pain will naturally weaken a lot.
