Why does a young person's knee hurt after being exposed to air conditioning for a long time, and what should be done about it?

Prolonged exposure to air conditioning causing knee pain in young people may be due to physiological factors, and symptoms usually improve after taking proper warming measures. However, it could also result from pathological causes such as trauma or synovitis, which require treatments like heat application or medication. The details are as follows:

I. Physiological Factors

Extended exposure to cold air from air conditioning may allow coldness to penetrate the knees, leading to poor blood circulation and resulting in pain. Symptoms typically subside once adequate warmth is maintained.

II. Pathological Factors

1. Trauma

If the knee has recently suffered trauma, exposure to air conditioning may exacerbate local tissue damage, causing pain. Patients should promptly apply heat to the affected area to help relieve discomfort.

2. Synovitis

This refers to an inflammatory response triggered by irritation of the synovial membrane, possibly leading to fluid accumulation in the joint. Prolonged exposure to air conditioning can worsen the inflammation, resulting in pain. Patients should follow medical advice and use medications such as loxoprofen sodium dispersible tablets, ibuprofen sustained-release capsules, or celecoxib capsules for treatment.

In addition to the above factors, knee pain might also be caused by degenerative osteoarthritis, rheumatoid arthritis, patellar chondromalacia, or other conditions. When discomfort occurs, individuals should promptly visit a hospital for evaluation to determine the underlying cause and receive appropriate treatment to promote recovery.
