I got a port November of 2013. It's actually a double port, so I have two access points instead of one. My only complaint is that, as a female, coving up an accessed port is more difficult that covering up a picc dressing. And really, that's a problem that's pretty low on the serious rating, haha.
When I'm accessed, I can't swim (my preferred exercise), but I do pretty much everything else. I also do yoga, and I noticed some positions felt uncomfortable, accessed or not, and so I've tended to shy away from those or alter them just slightly.
Mine is placed on my upper left chest. When I'm at my normal, healthy weight, it sticks out a little, but not too much. The scar stands out more than the port, really. I didn't do much for about a week, maybe a week and half after getting the port. The pain went away fairly quickly, but I felt an uncomfortable sensation for a few days.
I request certain needles so the profile stays low. We tried needles that came with a "buffer," but those stuck out too much for me, and they were difficult to cover. Now I use a lower profile needle.
