It was yesterday. I'd had some bloods done, thought I was all clear but got asked to call the surgery. Phone appointment made, and the doctor called yesterday just after 9. Apparently I have some strange protein levels in my blood, which means I might well have a blood cancer called Myeloma. More testing to be done urgently.
No pity asked for, I'm very Zen about it, but it was quite a shock. Que sera sera.
