Getting the port out is a lot simpler than having it inserted. I had mine out with just a local--which was not a pleasant process but I considered it a better option for me that having a line in for sedation. It took a bit of fiddling around but in the end I didn't have any problems. Apart from not liking it LOL.
I scar heavily and, predictably, that one is ropey and raised but I'm covered in similar and it doesn't worry me--just another battle wound. There is no 'hole' though--the port isn't that big and you won't see where it was. Relax, breath and you will be OK. Marg
