What's wrong with the soreness in my knees

Everyone's physical fitness is different. Some people lack trace elements in their bodies, such as calcium, zinc, and iron. Then your physical condition is relatively weak and you must supplement the nutrients your body needs. The knee is a critical part of the human body because people need support from the knee when walking. However, the knees are also prone to disease problems. For example, what is the cause of soreness in the knees?

1. Swelling and pain behind the knee, limited movement: Popliteal cysts are clinically more common in middle-aged people and have the highest incidence rate, more common in men than in women, leading to mechanical limitation of knee extension and flexion, mild pain, and obvious feeling of tension and swelling. Patient complaints are often characterized by gradual swelling in the popliteal area, accompanied by pain behind the knee. Occasionally, cysts can compress and obstruct venous return, causing calf edema. When the cyst grows to a certain size, the flexion and extension of the knee joint will be limited.

2. Infrapatellar pain: One of the signs of patellar instability. Tenderness is mostly distributed at the inner edge of the patella and the medial retinaculum. When the examiner presses the patient's patella with the palm of his hand and performs flexion and extension tests, subpatellar pain can be induced. Clinically, the tender point is sometimes inconsistent with the pain site complained by the patient.

3. Patellar pain: In the early stages of patellofemoral pain syndrome, the knees will hurt when walking, going up and down stairs, squatting and standing up. In severe cases, the knees will suddenly lose strength while walking, and the patient may even become unable to stand steadily.

4. Soreness and swelling at the tibial tubercle: Tibial tubercle epiphysiitis is common in adolescents aged 12 to 16 who often engage in strenuous exercise, more often in males than in females. It manifests as soreness and swelling at the tibial tuberosity and is a knee disease caused by overuse.

5. Anterior knee pain: Patellar anterior knee pain syndrome is a professional term to describe pain occurring in the front of the patella or around the patellar tendon. Patellofemoral anterior knee pain syndrome, also known as anterior knee pain, is caused by abnormal movement of the femur when the knee joint is flexed.

2How to prevent knee joint pain

The human body's bones need calcium to supplement nutrition. As long as there is enough calcium, the bones will be hard. If there is a lack of calcium, the bones cannot withstand pressure. Once under pressure, the joints will cause pain.

1. High-calcium diet: This is a fundamental measure to prevent calcium deficiency and is also an economical and safe method of calcium supplementation. The WHO specifies that the preventive dose of calcium is 500 mg per person per day, and the therapeutic dose is 1000 mg per person per day. Usually the absorption rate of calcium in food is only 30%. Milk and soy products are good sources of calcium. Other foods high in calcium include dried shrimp skin, kelp, seaweed, oysters, seaweed, sesame paste, etc. Animal bone soup is also rich in calcium, but you need to add some vinegar during the cooking process to promote the dissolution of calcium and facilitate calcium absorption.

2. Appropriate amount of protein: It is best to choose high-quality protein, such as eggs, lean meat, fish, shrimp, chicken, soy products and other foods. However, excessive protein will produce acidic substances during metabolism in the body, which will increase the excretion of urinary calcium and lead to increased calcium loss in the body.

3. Eat more foods rich in vitamin C: such as fresh vegetables and fruits, which can promote calcium absorption and are beneficial to the formation of bone matrix. However, it should be noted that some vegetables (such as spinach, water spinach, wild rice stem, winter bamboo shoots, etc.) contain more oxalic acid, which can combine with calcium to form insoluble calcium oxalate, affecting and preventing the body's absorption of calcium. Therefore, middle-aged and elderly people should boil these vegetables in water before eating them to remove the oxalic acid in the vegetables.

4. Low-phosphorus diet: When blood phosphorus increases, blood calcium decreases, and calcium absorption from the intestine is also poor. Therefore, you should eat less high-phosphorus foods, such as cola.

5. Low-salt, low-sugar diet: Develop a good lifestyle and habits, quit smoking, limit alcohol, and drink less coffee to eliminate obstacles in the calcium absorption process.

Appropriate exercise: Reduced exercise can easily cause calcium to be removed from the bones, leading to loss of bone mass and causing osteoporosis. Therefore, middle-aged and elderly people should regularly participate in physical exercise, such as walking, swimming, and Tai Chi, to increase bone toughness, increase bone mass, and improve the ability to resist fractures.

It is not recommended that children and middle-aged and elderly people receive more sunlight exposure, which can promote the synthesis of vitamin D3 and thus increase the absorption of calcium from the small intestine. Since ultraviolet rays cannot pass through glass, clothes, dust, smoke, etc. can block the passage of ultraviolet rays. Therefore, when sunbathing, you should try to make your skin directly contact with the sunlight. Do not sunbathe through glass. Only in this way can you get good results.

When choosing calcium tablets, you should listen to your doctor's advice. It is recommended to take calcium gluconate, calcium lactate, or Calcium Trace calcium tablets.

3 Ways to Treat Knee Pain

What are the treatments for knee pain? Treatments for knee pain are mainly divided into two categories, one is daily recovery, and the other is going to the hospital for physical therapy.

1. Daily recovery can start from the following aspects.

1) Lie flat on the bed, stretch your legs, and lift them up repeatedly 100 times, exerting force during the process. It should be noted that the left leg and the right leg cannot be raised at the same time, just alternate.

2) Change your existing exercise methods. If you experience knee pain, you should stop activities such as mountain climbing. You can try other sports such as swimming and rowing.

3) When walking or running, you should be steady and slow, not too fast. When riding a bicycle, you should not exert too much effort, especially when climbing a hill.

4) Avoid squatting for long periods of time and try to relax your kneecaps as much as possible.

5) Keep your knees warm in winter.

6) Soak your feet in ginger water every day to promote blood circulation. This method is very effective for knee pain caused by cold.

2. From a medical point of view, narrowing of the knee joint space, knee trauma, knee joint hyperplasia, knee synovitis, knee joint effusion, etc. can all cause knee pain.

1) Patients can receive acupuncture treatment, massage treatment, surgical treatment, etc. according to their needs.
