Can I have my brain back, please?

Feeling well chuffed with myself I've gone for my walk and am puddling about in my kitchen. All of a sudden I become aware of this weird feeling down the left side of my head so I blow my nose, sniff, shake my bald noggin about and pull faces. The weirdness persists.
'What new hell is this?' More  sniffing, blowing and shaking. Do I need to start stressing? Googling? What is it? 
Anyway, thiis nonsense goes on for twenty minutes and by now I've convinced my self it's getting worse. Some sort of precursor to a stroke? Why me? Why now? This was looking like a good day...
So I trudge off to the shower with my head on sideways wondering what to do next and the end of my earbud drops out of my ear and rolls across the bathroom floor. Crisis averted.
Seriously. Can I have my brain back please?
