I was very nervous and apprehensive
Eg how does it happen?
How do the holes heal up?
Will it hurt when they pull it out?
In fact it was no real problem
It took around an hour. Lots of prodding but all under local anesthesia
They have to find a cusp in the line that holds it in place. Then basically cut all the edges off the cusp, then the line justs slides out. The Registrar held his hand over the place, and within a minute it had sealed up - like magic
A few stitches and 'job done'
