Why does the weather change? Will the chest ache faintly? Poor breathing?

The change of weather is also a process from quantitative change to qualitative change. Generally speaking, the cumulative effect of meteorological factors reaches a peak on the day when the weather changes, which is more common before it rains: the humidity increases, the air pressure decreases, and the excessive change of air pressure will cause adverse reactions, low air pressure and low dissolved oxygen in blood (air pressure will directly affect the dissolved oxygen in human blood, and the higher the air pressure, the stronger the dissolved oxygen capacity), leading to accelerated heart rate, shortness of breath and fatigue and emotion. Chest tightness and poor breathing are related to atmospheric pressure and air humidity It's a normal phenomenon, just like when it's going to rain, it will be boring. Electrocardiogram should be done when chest pain occurs. If it is normal, the pain caused by heart causes should be ruled out. Intercostal nerve is a kind of nerve along the chest rib, which passes through the side abdomen from the back to the chest. Intercostal neuralgia is a semi-circular severe pain that passes through the chest and abdomen along this nerve. If it is intercostal neuralgia, the pain will depend on the intensity of coughing or breathing, and in severe cases it will cause dyspnea. Generally, inhalation is painful, but exhalation is not. However, it should be noted that it is sometimes mistaken for intercostal neuralgia, but it is actually pleurisy or angina pectoris. True intercostal neuralgia has three characteristics. One is the tenderness point on the side of the back bone, the other is the tenderness point under the armpit, and the third is the tenderness point on the side of the chest, which hurts when pressed lightly.
