Porta cath

I'm curious if anyone here has ever had a portable cath put in. I'm seriously considering getting one. I have no veins left. I've been getting poked for IV’s, on average at least six or seven times. Usually they don't get one in. And if they do, it is in one of my feet. Which is even more unpleasant than I ever thought it could be. I have so much scar tissue on IM injection sites that most shots don't work. My doctors have decided that a Porta cath is my best option to actually get my meds to me. Not to mention, that this way I can get my Benadryl cocktail, instead of Demerol or Morphine. Which is a big plus. So I was curious if anyone had any experience with them. Thanks for any info.
