when people get a birth control implant in their arm, what keeps it from moving around and cutting up flesh?

Question

I get that they aren’t sharp, but u don’t understand why they wouldn’t still move around or cut through muscles/tendons/veins.

Answer 1

Your body has two ways of dealing with foreign invaders: killing and disabling. It will send out white t-cells first to deal with the implant and an inflammation will indicate their losing battle. After this has failed the body will build cells around the object and encase it in an inert goo like structure. This will scarrify and attach itself to surrounding tissues stopping it from moving.
