Went to Plymouth on Tuesday for the day and had the troublesome wire in my sternum removed under general anaesthetic.
Very painful after local anaesthetic wore off: I am taking various painkillers but still pretty bad, though very gradually improving. My frozen shoulder had been slowly improving, with noticeably more movement possible, but this has made it much much worse again. I can’t work out what connection there might be with the op, but hopefully the problems won’t last long.
Can’t complain, I am in far better condition now than I had been for months.
