If you are one of those people who is constantly cracking their knuckles but also worrying about doing some long term damage to them, fear no more according to new research published in the Journal of Manipulative and Physiological Therapeutics. The cracking or pop sound you hear when you manipulate your fingers just so is usually the same sound as you hear in other parts of your body. Granted it seems more severe to hear your back than your knuckle make such noises but root causes are generally relatively benign and will not lead to any sort of arthritis or joint damage. Of course if any sound is ever accompanied by any pain or something doesn’t seem right, always consult a doctor. Now we just need to find a way to stop our fretting and get back to enjoying the good life. Ahhh, if only it was that easy.
