Introduction
Knee discomfort when the weather turns cold may be related to physiological responses, overuse, osteoporosis, osteoarthritis, rheumatoid arthritis, and other factors. It is important to seek medical attention and receive targeted treatment under a doctor's guidance. If symptoms of knee discomfort occur, prompt medical evaluation and treatment are recommended. Maintaining a healthy diet and adequate nutrition can help strengthen the knee's resilience.

Discomfort in the knees when the weather turns cold may be related to physiological responses, overuse injuries, osteoporosis, knee arthritis, rheumatoid arthritis, and other factors. It is important to seek medical advice for proper diagnosis and targeted treatment. If knee discomfort occurs, prompt medical attention is recommended. Specific causes are analyzed as follows:

1. Physiological Response

When the weather gets colder, the knee joints may be stimulated by the cold, leading to slowed local blood circulation and reduced blood flow, which can cause symptoms such as localized pain and stiffness in the knee joint. Appropriate heat application or massage can help improve local blood circulation and relieve pain and stiffness.

2. Overuse Injury

Knee overuse often leads to local inflammatory reactions that affect normal joint function. Cold weather may intensify this inflammation due to cold stimulation, resulting in knee pain and stiffness. Engaging in appropriate physical activity can help alleviate symptoms of knee overuse. Low-impact exercises such as walking, jogging, and yoga are recommended. Care should be taken during exercise to protect the knee joints and avoid excessive strain.

3. Osteoporosis

In severe cases of osteoporosis, decreased bone quality increases pressure and friction between joints, causing knee pain and stiffness. Cold weather may worsen these discomforts due to cold exposure. Therapies such as ultrasound and electrical stimulation may promote bone metabolism and blood circulation, helping to reduce pain and stiffness.

4. Knee Arthritis

Knee arthritis is an inflammatory joint condition. Cold weather may exacerbate joint inflammation due to cold stimulation, leading to increased joint pain and stiffness. Under a doctor's guidance, medications such as aspirin tablets, ibuprofen tablets, or naproxen tablets may be used for treatment.

5. Rheumatoid Arthritis

When temperatures and humidity drop in cold weather, secretion of synovial fluid in the joints may decrease, increasing surface friction and resulting in pain and stiffness. Under medical supervision, medications such as methylprednisolone tablets, celecoxib capsules, or indomethacin tablets may be prescribed for symptom management.

Maintaining healthy eating habits and adequate nutrient intake can help strengthen knee resilience. Choosing suitable forms of exercise, such as walking or tai chi—focusing on gentle movements—can support joint health while avoiding excessive stress on the knees.

Can lamb testicles improve weakness and soreness in the waist and knees?
Lamb testicles, commonly referred to as "yang dan," generally have limited effectiveness in improving symptoms such as soreness and weakness in the waist and knees. They are unlikely to provide significant relief for mild symptoms caused by excessive fatigue or for more pronounced symptoms resulting from underlying diseases. Lamb testicles should be thoroughly cooked before consumption, and intake should be moderated to prevent indigestion.
