 * 1) Piercing Migration


 * __Piercing Migration__
 * **en.wikipedia.org/wiki/Piercing_migration**
 * Definition: movement of initial piercing to a different location
 * Painful or go unnoticed until progressed
 * E.g. a ring can migrate outside the skin
 * Cause and effect:
 * Effects can vary widely but most common form involves migration of heavy small gauge earrings downwards out of earlobe (“cheesecutter effect”)
 * Modern jewelry more balanced in weight to gauge ratio
 * Play + movement can also lead to migration but less likely
 * Occur without open wound created (fistula stretches in one direction and tissue fills behind)
 * Not uncommon with tongue piercing but stops before exit body
 * Damage to tissue surrounding piercing: during healing it may move toward direction of wound since fistula is not as strong
 * Body can also reject material which cause migration (irritation of surrounding tissues) but this is rare due to surgical grade material
 * Pressure also causes migration to improper piercing (custom jewelry helps)
 * This can couple with rejection of body due to improper drainage (length of piercing)
 * Rejection rate: chance piercing rejected by body (surface piercing have higher chance to be rejected)
 * **www.bodyjewelleryshop.com/body_piercing_information/common_body_piercing_problems.cfm#migration**
 * Common misconception: piercing moving through entire body
 * Usually just moves few millimeters from original position (“Parking”)
 * May be allergic to metal or jewelry is too big (e.g. Navel piercing)
 * It is difficult to heal if it puts stress on tissue it rests in
 * This requires change in jewelry size/shape
 * Weight + time will show signs of migration: require change to light weight metal or more biocompatible plastics
 * Smaller gauge jewelry is easier to migrate (abdominal and genital)
 * If migration is unchecked, it leads to rejection
 * Effects: sore skin, red, thinning out skin, scar tissue, indentation

 * Improper jewelry selection can cause naval/eyebrow piercing to grow out starting from outside moving inward
 * Impossible to place back into original position (require re-pierce or removal)
