Had my second fill yesterday morning. My fills have been difficult: they have a hard time finding the port and then are unsure if they are in the right spot because they can't get good fluid return. So they poke and prod for awhile. She did find it, filled it and had to take some out because I couldn't swallow water. After that everything felt fine. I have no problems with liquids. I jumped on the treadmill last night for a slow pace walk...2.5...and had lower right sided pain, like a stitch in my side. It's well below my port site. I stopped walking and still had pain. This morning I was fine when I woke up, but now that I'm walking more at work, I have pain. My guess is the poking around jacked up my muscle and I'm having pain from that, but would love to know if anybody else has experienced this.

I had my first fill on Tuesday. I felt pretty uncomfortable in the port area for a couple of days. I do think all the pushing a prodding around is what may be making you sore. If it gets worse though, I would call your doctor's office and inquire.
