Remicade/Trouble with IV

Hello All, new here. Daughter has Crohn's, she is 14. Overwhelming to be making huge decisions for someone else, so I am constantly researching for her. She has been on Remicade for over a year now. No major problems with the meds. First few infusions were like a miracle! She could eat anything she wanted. Seems to have lost some of it's power now. We never had problems with her veins before, but now the past 2 times her veins keep "blowing". Time before last her hand puffed up and bruised so bad. I thought the nurse just wasn't very good at it. This last time she had 6 needle sticks and 5 veins blow. It was so bad. She was wrapped with warm towels, I can't believe she didn't cry! I wanted to. They finally gave her infusion in the wrist which was very uncomfortable.
Has anyone on here had this issue after starting the infusion? And is it very common to do a port with Remicade? She goes every 7 weeks for infusions, so I didn't think they'd do one but I'm nervous about the next infusion and how her veins will hold up. Thanks for any insight! :)

I have been on Remicade since October, 2008. The first several times I got my infusions, I would show up at the site and the nurse would ask where my port was. I would tell them that I didn't have one and they seemed very shocked by this. In June of 2009, I had an infusion port placed in my left chest and it has been a God-send ever since. It is really only used for my Remicade infusions, but at least I don't feel like a pin cushion every time I have to get a treatment done. I would definitely talk to you daughter about the benefits of having a port placed and then if she is okay with it, I would talk to the doctor about having one put in. I get my infusions every 8 weeks and have to go at the four week point to have the port flushed to make sure it stays open and functioning well.
