I forgot to say, on Saturday there was a lady at our table at supper who had had a similar cold/flu virus, it seems to be going round, it is mild flu or a bad cold, and it is bad for asthmatic people, the lady on our table was asthmatic and she described the same symptoms as me, even the sudden high temperatures, I was relieved to know that it wasn't just me, she said her temperature rocketed up and down, which was what mine had been doing. I am now recovered, and she was also just about recovered.
