I assume your talking about 'drawing blood' thats what butterfly needles are used for. They do have smaller gauges, like a pediactric needle can be used depending on the medication, and I'm pretty sure remicade can go through it.
It took years of the ER complaining that I had horrible veins, even IV therapy could rarely get them in me, I would always have to wait extra long because they'd end up having to go in the tops of my feet, which you need drs approval for because of risk of infection. My surgeon said the nurses were just lazy, which I found sort of humerous, but I see they just wanted to have me not get poked and prodded so much for my own comfort, I'm so used to it it didnt bother me anymore. Eventually I asked myself and did get a port, the brand name is powerport, which I've read is the only port that is actually suitable for use with a CT scanner, for the dye. Because of the pressure the CT puts on the tubing it'll blow out most ports so be sure to ask about this. It really wasnt a bad time getting it in, I mean for me now it was considerably harder because all of my viens and arteries were considerably smaller, I first went in the OR so my surgeon could do it and he couldnt get it, he tried twice while in the OR, then he stopped and sent me to an interventional radiologist, which went smoother but they didnt understand my tolerance the least bit so I basically was like taking tylenol to go through this invasive procedure. I have to admit though the port itself is very nice and very practical. But it is my luck that once I get it installed I dont use it nearly as much as I used to use my viens. But I dont have to wait for someone with better skills as an phlebotomist nor to get drs approve to go in my foot either. So first try and I'm good.
Seems to me your not being treated agressively per se, and Remicade alone isnt much, most people are on considerable amount of medication before and while on Remicade. as a matter of fact I think I've heard and read numerous times that remicade has had better results in conjunction with medications like Prednisone. or even Methotrexate.
