Arthritis is a common condition characterized by joint pain, yet there are several misconceptions surrounding the disease. Here are three prevalent myths about arthritis that need to be debunked.
1. Can cracking your knuckles lead to arthritis?
Contrary to popular belief, cracking your knuckles does not cause arthritis. When you crack your knuckles, the small blood vessels and nerve endings around the joints are stimulated, which can improve local circulation and help relieve pain caused by spasms and reduce inflammation. Additionally, knuckle-cracking does not cause joint enlargement, as this is actually due to bone growth resulting from joint damage.
2. Does a popping sound in the joint indicate arthritis?
Many people hear a popping sound in their knees when sitting down or standing up and worry that it might be a sign of arthritis. However, this noise is often caused by the vibration of gases within the joint cavity. The human joint cavity is filled with synovial fluid, which acts as a lubricant and cushion. When the joint moves, a distinct gap forms in the middle of the joint cavity. Gases from the surrounding area diffuse into this gap and, together with the liquid, produce a crisp popping sound. If a medical examination confirms that there is no joint pathology, then it is simply a case of “noisy knees” without any underlying condition.
3. Is there a link between cold weather and arthritis?
In fact, arthritis is not caused by the cold. Cold and damp weather does not cause or exacerbate osteoarthritis, but it can make the symptoms of arthritis more pronounced. The onset of arthritis can be due to various factors, including improper protection during physical activity. Older individuals, those who are obese, and people with sedentary lifestyles may also experience chronic knee pain. The increased perception of pain in cold weather could be because prostaglandins, which contribute to pain, accumulate in the knee joint at lower temperatures, making the pain more noticeable.
It is essential to dispel these myths about arthritis to better understand the condition and approach it with the right knowledge.
