Mine is in the same place as yours but goes under my collarbone. However, I can still trace where they "tunneled through" from the port until about my collar bone. Now I can still feel it if I look for it, but it doesn't hurt anymore. As well as the incision pain, I had a lot of muscular pain in the first week or so because they had trouble making a pocket for mine and apparently moved things around quite a bit in the process. After it heals it doesn't hurt anymore--it's just noticeable if you bump into it.
I do think you'll like it much better once you're used to having it.
