I think you'll be happier with the port.
I had mine put in as outpatient surgery. They used twilight sleep and I don't remember anything. It was sore for awhile but not anything like when I had my lumpectomy, so for me it was not a issue. The main problem I had was trying to lay on that side and it pushes the port area and was uncomfortable for some time.
Also if your seatbelt goes across where your port is, it's a pain.
But overall, I'm happy with my port and not having to be dug around on to find a vein.
From what I've been told, there's much less of a risk of infection with a port, than a pic or central line, just due to it being under the skin.
For me my port is (most times) just a bump under my skin, and I forget it's there.
When I was in between chemos for a few months, I had the port flushed once a month while at my Oncologist appointment.
Hope everything goes well for you.
