Why do both knees ache?

Generally, soreness and pain in both knee joints may be caused by aging, overuse of the knees, cold exposure, meniscus injury, knee arthritis, and other related factors. If discomfort occurs, please seek medical attention promptly. Detailed explanations are as follows:

1. Aging

With aging, the elasticity and thickness of joint cartilage decrease, and secretion of synovial fluid reduces, leading to diminished lubrication and increased joint friction, which can easily cause pain. Maintaining appropriate exercise, such as low-impact activities like walking or swimming, can help strengthen muscles and support the joints.

2. Overuse of the knees

Excessive use can cause excessive friction and stretching of the cartilage and ligaments in the knee joint, triggering an inflammatory response and resulting in knee soreness. It is recommended to rest appropriately, avoid activities that repeatedly cause pain, and apply ice to the knee area to reduce the metabolic rate, thereby decreasing the accumulation of waste products and inflammatory mediators, which may help alleviate symptoms.

3. Cold exposure

When the knee joint is exposed to cold, local blood vessels constrict, slowing circulation and causing the buildup of metabolic byproducts within the joint, which can lead to soreness. Keeping warm, especially around the knee area, is important. It is recommended to use moxibustion under the guidance of a qualified physician to stimulate meridians and acupoints, promote blood circulation, and achieve the effect of unblocking meridians and relieving pain.

4. Meniscus injury

A meniscus injury is primarily caused by external impact or excessive rotational movement during physical activity. After a meniscus injury, joint stability decreases, which may lead to symptoms such as pain and swelling, including localized tenderness. It is recommended to follow medical advice for the use of medications such as glucosamine sulfate capsules, ibuprofen sustained-release capsules, and Tongluo Qutong plasters for treatment.

5. Knee arthritis

Age, obesity, inflammation, trauma, and genetic factors may all contribute to the development of knee arthritis. Due to cartilage wear and degeneration, inflammatory responses occur within the joint, causing symptoms such as pain and swelling, which may be accompanied by swelling and limited mobility. Patients should follow medical advice to use medications such as loxoprofen sodium tablets, Huoxue Zhitong capsules, and celecoxib capsules for treatment.

Maintaining sufficient sleep and regular作息 habits can help promote physical recovery and enhance immunity.
