Thanks everyone
4-Eyes (feel bad calling you that

) - I am looking at something that would be left in for a long period of time too. In addition to Tysabri (and I have no real idea how long I will be on that, but am thinking quite some time if things stay as they are), but I also have to have blood tests taken on a regular basis, and I have ITP, so IVIG and possible blood/platelet transfusions have already been, and are very possibly on my agenda in the future).
I do have a few questions for you - was going to PM but couldn't for some reason. Did it hurt much after the surgery? Did you bruise/scar much from the implant? Is it really visible? How often (if ever - I guess it depends on your usage) do you get it flushed - do you do that yourself, or done by a nurse? Does it hurt when they access it? Is it tender or uncomfortable when not in use?
Many thanks to you all for the information.
