Why is the place where the fracture occurs uncomfortable in rainy days?

Many people may have had this experience: after an injury or surgery, the injured part or wound will be uncomfortable one or two days before it rains and cloudy, just like the weatherman. "Doctor, when I'm well, it won't rain on cloudy days, will it?" This is also the most frequently asked sentence by surgeons.

Many patients' soft tissue injuries have recovered and are basically normal at ordinary times, but they are afraid of cold, wind and weather changes. When the wind blows, it's unbearably cold. It is very painful to wear thick clothes in hot summer. It is estimated that many people don't know why this is, so I will give you an analysis today.

First of all, learn about our own skin: skin includes epidermis, dermis and subcutaneous tissue. Nerves exist in dermis and subcutaneous tissue. If the injury goes deep into dermis and subcutaneous tissue, it may form scars. New blood vessels and nerves also grow in it.

When the weather changes, especially before the storm, the atmospheric humidity, pressure and temperature will change obviously. Nerve endings in scars can sensitively detect this change. The thinner the nerve fiber, the more sensitive it is to external changes, and the local symptoms will be painful or itchy.

The regulation of vasodilation in scar is different from that in normal tissue. After being stimulated by cold, humidity or low air pressure, blood vessels continue to contract, blood flow decreases or flow rate slows down, metabolites cannot be eliminated in time, and local blood supply is insufficient, which reduces the tolerance of scar tissue to pain. Scar tissue will also shrink due to stimulation, and it will also stimulate nerve fibers to be squeezed or pulled, thus causing pain in old wounds.

How to prevent and relieve pain and discomfort;

1, according to the weather changes, timely increase or decrease clothes, do your own cold and warm work. Especially don't be attacked by humidity and cold.

2. Adjust the local environment: try to keep the living or activity places dry and away from damp and cold places. Go out less in rainy days.

3. Strengthen physical exercise, improve physical resistance and adaptability, maintain a happy mood, and eat more foods rich in vitamins, calcium and phosphorus.

4. Massage, massage and rub the injured part properly at ordinary times to improve local blood circulation. Soften scars and relieve symptoms of nerve compression.

5. If you feel unwell, you should treat it in time: you can apply rheumatism cream and safflower oil. Can be applied locally with hot towels, hot water bottles, etc. You can also choose Shangshi Zhitong Ointment and Goupi Ointment for external application. You can also go to the hospital for physical therapy such as ultrashort wave, infrared ray and pulsed electric wave, so as to increase local blood circulation, dispel cold and dampness and relieve symptoms.
