Well, that was a fun evening & night. After my last post I rapidly felt more & more wobbly & started shivering uncontrollably, so went to bed. When Mrs B came home from work she took my temperature - 40.8C - then phoned 111, who said the standard "rest, keep warm, drink plenty", what circumstances to call again (or even 999) & to call my GP in the morning.
Temperature's down 3 degrees now, shivering's stopped, headache, earache, sore throat, painful sinuses (complete with ache in back teeth, now gone), tight throat & tender neck all still present but eased, & coughing fits reduced. Still feel washed out, though: weak, wobbly, & now occasionally coughing up unpleasant-coloured muck. Spoken to GP who said to come in later. Complicated by the bashed bones in my face, I think.
Again, bugger! It's a lovely day & there are things I want to do.
