My knee often hurts in rainy days. Is it a cold?

In daily life, we often find that whenever the temperature changes or it rains, many people complain about knee pain, just like the weather forecast.

Why does the knee ache when the weather changes?

Knee pain, you can first consider the problem of arthritis, knee osteoarthritis is a common cause of knee pain.

.

When the weather changes, especially when it is about to rain, the air pressure will generally decrease and the humidity will increase, so that the liquid in the cells of healthy people will seep out by itself, resulting in an increase in urine volume to adapt to the weather changes.

For arthritis patients, due to the existence of diseased tissues, the liquid in the cells can not be discharged in time with the change of weather, which leads to the cell pressure in the diseased area higher than that in the surrounding normal tissues, which will cause swelling and pain in the diseased area. This is one of the reasons why arthritis patients can predict weather changes.

In addition, in the theory of traditional Chinese medicine, arthritis is considered to be the result of wet evil entering the body, so when the temperature drops in rainy days, the human body needs faster blood flow to resist the cold. However, the blood flow in the blood vessels of arthritis patients is slower than that of normal people, and the body can't take timely and effective measures to resist, so it will cause blood congestion at the joints. As the saying goes, "it hurts if you can't do it", impurities and oxygen in the blood will aggravate the inflammation of joint tissue and surrounding muscles.

How to relieve joint pain?

1, weight control: losing weight is the most direct way to protect the knee joint, because the greater a person's weight, the greater the weight borne by the knee joint, and the faster the knee joint wears and ages.

Studies have shown that joint pain can be reduced by 20% for every 5 kg weight loss, and weight loss plus appropriate exercise is as important as or even better than drug treatment.

2. Moderate exercise: Moderate exercise can increase local blood flow of joints and relieve pain.

3. Keep your knees warm: Keep your knees warm in harsh environment or cold weather to avoid knee pain caused by cold, wind, cold and humidity. Once you find joint pain, you can't take it lightly. You should consult a professional doctor to avoid arthritis.

.

4, diet conditioning: daily diet needs to pay more attention, scientific and reasonable diet is an important measure to prevent some arthritis. For example, reducing the intake of foods rich in purine can effectively prevent gouty arthritis.

5, a positive attitude-pain is temporary, the body will quickly adapt to changes in the weather, and bad weather is easy to make people feel bad, and bad emotions themselves will aggravate the sensitivity of pain;

If necessary, increase the dosage of analgesic drugs or combine them under the guidance of a doctor.

How to treat osteoarthritis?

Regarding the treatment of osteoarthritis, in addition to joint replacement, some conservative treatments are mainly used in clinic.

.

Referring to the clinical guidelines of the American Orthopedic Association, it is suggested that:

1, strengthen strength

Muscle strength training, strong enough muscle strength, can protect joints and support joint stability. However, we should pay attention to avoid strenuous exercise that excessively aggravates joint load.

Step 2 take painkillers

It is recommended to use anti-inflammatory and analgesic drugs orally or locally to treat joint pain.

Step 3 lose weight

If the body mass index (BMI) exceeds 25, lose weight! Relieve the pressure on joints such as knees.

.

4, surgery when necessary

If there is limited joint movement or severe pain, it is recommended to do MRI examination to determine whether there are loose bodies in the joint or obvious cartilage rupture, and whether timely surgery is needed.

5. Don't use health care products indiscriminately.

Don't pin the hope of curing osteoarthritis only on health care products, and you need to cooperate with regular treatment.
