Does rheumatoid arthritis cause cracking bones not literally like breaking but cracking noises?

This noise, unless, painful, is due to air in the joint. See link below about joint popping.


Does clicking your fingers spoil the shape of fingers?

I'm guessing by clicking you mean the sort of popping action people do when they sort of push their knuckles. This is completely harmless in the long term and will not misshape you fingers, make your fingers shorter or give you arthritis. It's all just an urban myth. When you do click your fingers or pop your knuckles the sound isn't the bone cracking or hitting against another bone, it's simply a small bubble of trapped air which squeezes its way free through a small space. Kind of like poking a balloon with a pin. It creates a small hole and all the air tries to escape at one making a bang. That's all it is. Nothing damage, nothing to worry about. Unless you do it too hard and break something :P But that's not likely to happen.


what does it mean if you can hear your finger joint move?

If popping can be heard in the finger, it is possible it is only cracking the air bubbles; however, if popping can be heard as well as the finger causing pain with noticeable swelling, it is likely it is dislocated.


What part of a skeleton system allow bones to move?

The ribs expand so that we can breathe. When the ribs expand, the volume of the pleural space increases and the lower pressure brings in air.

Is it good to be constantly cracking your knuckles?

Most people say cracking knuckles leads to arthritis. It doesn't! I wouldn't recommend cracking your fingers all the time, and I personally don't like cracking fingers in the cold. You can, if you want to, but it hurts. I think the weather of the cold air affects the finger joints which make them stiff and harder to crack. Cracking your fingers also open your joint air holes, so you'll be okay. Cracking fingers are mostly fine to do!!

If air has been introduced under the skin, it could cause a popping-crackling sound after surgery. The patient should bring this to the attention of his or her physician. Typically, these small air bubbles are re-absorbed by the body but the surgeon should be made aware so the area can be assessed.
