I had to have regular sessions whilst being treated for a severe leg (cellulitis) infection and kidney failure a year or so ago. I had "line" inserted in my neck , in order to connect me to the dialysis machine next to my bed; it was initially rather frightening,but I soon got used to the noises and flashing lights ,and was told that , in the event of a power cut, my blood could be returned to me with the aid of a built-in hand pump ! It is possible that Reading Hospital now has more modern apparatus.The big downside , of course,is that the process will remove substances like pain-killers,such that you can ,sometimes, end a session by feeling nauseous ; not pleasant, but better than ....well, you know !Anyway, I survived a month of it (obviously ) and I wish you well.
