rather Quack.
Been off for the last three weeks with a lower back strain. Being a man, I have been muddling along with it since October, but it finally locked up as I was getting ready to fly back from Newark at the end of November.

First week self certificated, but being a man, didn't do anything about it for a week. Saw the quack who agreed it was muscular and signed me off for another week.
Still being a man, I eventually saw a chiropractor, and three visits later, almost fixed, last appointment was the day my first quack certificate expired but not quite ready to report fit for my duty last Friday.
Call quack to get it extended another week. Oh, she's not in for a week. Fast forward to this week, turns out she's given up until next year, so different quack was asked to issue another certificate to cover 13th to 19th as I am back to work tomorrow and need it for my return to work meeting.
Certificate arrived by text just now... Only signed me off from the 13th to 2nd of Jan

So now I need to waste my morning chasing up a correct certificate instead of getting ready for a night flight tomorrow... aka sleeping.
Moral of the story, if your back hurts, go straight to a chiropractor
