In medicine, there are two kinds of noises made by knees: one is physiological snapping sound, and the other is pathological snapping sound. Physiological sudden onset is harmless to the body, but if it is pathological sudden onset, there may be many reasons.
Physiological knee "ringing the bell" has four signs.
Bian Xiao even came up with a bold idea when he knew that physical snapping was harmless to his health. This kind of knee is a bit like the sound of a drumming point. Some people use guitars, others use bass, and Bian Xiao plays directly on his knees. But when I bent my knees again, I found that there was no noise immediately, and the band considered giving up. In fact, this is related to the characteristics of physiological snapping up:
1. The sound is crisp, single and not repetitive.
When the knee makes a sound, don't ignore the noise, but listen and analyze the characteristics of the sound. Pay attention to whether the sound is crisp and monophonic. If there is no pain, try to move your joints again and pay attention to whether the noise will last.
2. It only happens when the joint is suddenly stretched or bent.
Physiological snapping up is sporadic to a certain extent, mostly when the joints suddenly move. Just like squatting suddenly, the knee may break physiologically, or it will appear when you stand up after squatting.
3. Between two clicks, the joints must have a certain rest time.
Physiological fracture occurs because there will be some lubricating fluid at the joints where our bones touch each other. These lubricants will reduce the friction between bones, thus protecting our bones. There will be some small bubbles in the lubricating fluid. When we exercise our joints, bubbles will burst and make a snapping sound. The bubble will not form again soon after it bursts, so there will be a pause between the two rebounds.
4. If you have slight pain or discomfort, you will often feel relaxed after playing.
In fact, this snapping sound is quite common, which is the same as when we usually move our joints, break our fingers and turn our wrists. If this physiological burst occurs, it will not cause other discomfort, so no special treatment is needed. This snapshot is most common in teenagers with mature joints. Infants and young children will not happen, which is rare for children.
Young and middle-aged people are more prone to blink, and with the increase of age, this phenomenon will gradually disappear after entering old age. Moderate physiological tearing will be beneficial to joint activity, which is beneficial and harmless. It is worth noting that long-term intentional physiological snapshots may lead to arthritis.
