Wow...I am simply amazed at this....my son's central line was placed in the O.R. He was sore in his neck when he came out, but only for a little while...he said it was like a bee stinging him, but said he could handle it....then as far as the plasmapheresis went...he loved it...by the second treatment he was feeling better and after 4 he was like a normal 8-year-old boy...full of energy and smiling from ear to ear. I am soooo sorry to hear about your bad experience...keep your chin up and feel better soon!
