Should someone in their 30s bother about popping and cracking joints?
Well, the simplest answer will be.
As long as the sound does not come with any pain or swelling, you do not need to worry. Popping or cracking sound may be just gas bubbles bursting into the fluid around the joint, or the sound of ligaments and tendons being drawn and released.
Do you notice this more when you repeatedly move the joint (when you press the shoulder in the gym, for example)? A soft snapping or clicking sound is also sometimes caused by a tight muscle or tendon caused by a tight structure.
After reading your article, it reminded me of some things about gate io that I studied before. The content is similar to yours, but your thinking is very special, which gave me a different idea. Thank you. But I still have some questions I want to ask you, I will always pay attention. Thanks.
