Introduction
Pain at the right edge of the left knee is mainly caused by aging, excessive exercise, cold exposure, meniscus injury, and knee arthritis. With aging, the cartilage in the knee joint gradually wears down, joint fluid decreases, and the joint space narrows, leading to increased friction and pain. It is recommended to maintain moderate exercise, strengthen muscle strength, and preserve joint flexibility.

Generally, pain on the right edge of the left knee may be caused by aging, excessive exercise, cold exposure, meniscus injury, knee arthritis, and other factors. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

1. Aging

With aging, the cartilage in the knee joint gradually wears away, joint fluid decreases, and joint space narrows, leading to increased joint friction and subsequent pain. Maintaining moderate exercise, strengthening muscle strength, and preserving joint flexibility are recommended.

2. Excessive Exercise

Excessive physical activity or prolonged standing can place excessive pressure on the knee joint. High-impact activities such as running and jumping may easily cause injury to the muscles, ligaments, and cartilage around the knee joint, resulting in pain. Appropriate rest, reduced activity levels, and avoiding repeated injuries are advised.

3. Cold Exposure

When the ambient temperature is low and the knee area is not properly protected from the cold, the right edge of the knee may contract due to cold exposure, inducing spasms and pain. Applying heat therapy appropriately to promote blood circulation may help alleviate symptoms. Additionally, it is important to keep the knee area warm to prevent further cold exposure.

4. Meniscus Injury

Knee sprains and long-term weight-bearing squatting can lead to meniscus injury. When the meniscus is damaged, knee pain, swelling, and limited mobility may occur, along with symptoms such as joint locking and clicking. It is recommended to follow medical advice regarding medications such as diclofenac sodium sustained-release tablets, ibuprofen sustained-release capsules, and Tongluo Qutong膏 (pain-relieving plaster).

5. Knee Arthritis

Age, obesity, inflammation, trauma, and genetic factors may all contribute to the development of knee arthritis. The cartilage tissue in the knee joint gradually deteriorates and degenerates, leading to pain and functional impairment, which may be accompanied by joint stiffness and swelling. Patients should follow medical advice to use medications such as acetaminophen tablets, celecoxib capsules, and glucosamine sulfate capsules for treatment.

Maintaining adequate sleep duration and regular作息 habits can aid in physical recovery and enhance immune function.
