If cracking your knuckles truly did cause arthritis, this could potentially be a problem. However, there is no research showing that any damage occurs when you crack your knuckles. In fact, joints need movement in order to function properly. It is usually a lack of movement that causes problems such as arthritis.
The myth about arthritis being a side effect of cracking your knuckles was probably started by a mother who grew tired of her child cracking their knuckles so she told them that if they kept on, they would get big knuckles and arthritis. The child stopped cracking their knuckles, therefore this success story was passed on to others until the rumor became a modern day societal concern.
Misalignment in the spine results in certain vertebrae lacking movement or “getting stuck”. Proper joint mobility is critical for a healthy spine; chiropractic adjustments restore proper motion and allow the nervous system to flow as it was intended to flow.
