What causes knee soreness and pain when it rains?

Knee soreness and pain during rainy weather may be caused by physiological factors, or by pathological conditions such as osteoarthritis or knee synovitis. A detailed analysis is as follows:

1. Physiological Factors

During rainfall, low temperatures and high humidity can expose the knee joint to cold and dampness. This may cause spasms in the ligaments and joint capsule surrounding the joint, as well as contraction of the synovial membrane, leading to knee pain.

2. Pathological Factors

1) Osteoarthritis

With aging, degenerative changes in the knee joint can make it particularly vulnerable. When affected by cold and damp conditions, blood circulation and qi flow around the knee may become obstructed, resulting in pain. It is recommended to use topical medications such as anti-inflammatory analgesic plasters, musk bone-strengthening plasters, or injury-dampness pain-relief plasters under a doctor's guidance to alleviate symptoms like muscle soreness and joint swelling and pain.

2) Knee Synovitis

Lower temperatures may exacerbate inflammation and edema of the synovial membrane, causing knee pain. In severe cases, increased joint effusion may occur, leading to restricted movement. It is recommended to take medications such as diclofenac sodium sustained-release tablets, indomethacin tablets, or etoricoxib tablets under medical supervision to reduce inflammation, relieve pain, and alleviate symptoms.

In addition, rheumatoid arthritis or gouty arthritis could also be possible causes. It is advisable to visit a hospital for thorough evaluation and follow medical advice for appropriate treatment.
