Suddenly in the office on Friday I was freezing cold, went blue and was shaking uncontrollably, then a banging headache started. Made it home and crawled into bed and stayed there until just now, dragged myself down to the sofa. I've never felt this unwell in my life. I'm alternating between being soaked in sweat and freezing cold, my whole body, aches, I'm so dizzy I'm struggling to walk, I haven't eaten since Friday morning - feel sick even thinking about it.
I'm alternating paracetamol and ibuprofen. What's wrong with me? What else can I do?
