What are the causes of knee soreness and pain?

The knee may refer to the knee joint. Causes of knee soreness or pain include overuse, poor posture, osteoarthritis, synovitis, and rheumatoid arthritis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Overuse: Prolonged standing or running may lead to fatigue in the muscles and ligaments surrounding the knee joint, resulting in knee soreness. It is advisable to properly schedule rest and exercise periods, avoid prolonged continuous physical activity, and perform moderate stretching and relaxation exercises to help alleviate discomfort.

2. Poor posture: Sitting or squatting for extended periods may impair local blood circulation, leading to knee soreness, possibly accompanied by stiffness. It is recommended to maintain correct sitting and standing postures, avoid remaining in the same position for long durations, and try to stand up and move around every 40 minutes.

3. Osteoarthritis: This condition may be associated with joint wear and tear, obesity, and other factors. When local inflammation occurs, inflammatory mediators may trigger knee soreness, often accompanied by joint stiffness and audible cracking sounds. Patients are advised to follow medical instructions when using medications such as Glucosamine Hydrochloride Tablets, Gukang Capsules, and Diclofenac Sodium Sustained-Release Tablets.

4. Synovitis: This may result from local trauma, joint overuse, and similar factors. After onset, inflammatory changes in the synovial membrane may cause knee soreness, joint swelling, and other discomforts, possibly accompanied by joint effusion. Patients should follow medical advice when using medications such as Synovitis Granules, Ibuprofen Capsules, and Celecoxib Capsules.

5. Rheumatoid arthritis: This is generally caused by factors such as living in damp environments or microbial infections. Following local inflammation, inflammatory mediators may induce the aforementioned symptoms, along with redness, swelling, and fever. Patients are advised to use medications such as Qingpeng Ointment, Diclofenac Sodium Sustained-Release Tablets, and Methylprednisolone Tablets under a doctor's guidance to improve symptoms.

In daily life, patients are advised to keep warm, avoid staying up late, refrain from consuming spicy foods, and eat appropriate amounts of fresh vegetables such as radish, cabbage, and lettuce, which may benefit recovery.
