because Air gets trapped in the hole
If the ball on the end of the bar has closed inside your skin you will have to get it surgically removed. There is no other way of getting it out without seriously damaging your lip.
Do you mean that the skin had healed around the jewelry? If thats it, go to your piercer to have it removed.
If you mean a ball of hard skin, then it's only your body healing around your piercing. Since you have something permanent in there, it will heal around it and act kind of like a scar. If you remove it, it will still be there. I have that in my navel and septum.
The word rook does not mean anything I don't think. A rook piercing is located on the ear. Where your cartalidge ends and it is that little (hard you cant move it) flap of skin between the ear cartalidge and your tragus (that hard flap of skin on the inside of your ear in front of the hole)
A closed fracture is when the skin is still intact. A compound fracture is when the broken bone is sticking through the skin.
Yes once the body has had a chance to heal and toughen the piercing that tissue will soften up, it's what we call a guarding reaction.
That is a very good question! Open verses closed fractures make all the difference. In skin piercing or open fractures, you have contamination of the broken bone with bacteria. The bone infections are very difficult to treat.
No, oil dead skin would not affect an ear piercing. Sometimes people just have hole that don't close over time, even ten years.
You are over cleaning your piercing and drying it out
If you take out a piercing early, the skin will heal.
Puts a hole in it.
Actually, it is more a problem of how much skin is available in the piercing area, and how thick that skin is. Thin skin is more likely to allow the piercing to eject. Check with a licensed body piercer and let them assess your navel skin where the piercing would be.
