48 hours

Mostly have been spent here, in bed, avoiding light and any sort of movement.
My head hurt so much in the small hours of this morning that I feared something terrible was happening. Couldnt move to get painkillers, couldnt shout for Corin (spare bedroom, problem with shoulder!). Photosensitivity has passed, but headache reappears if I forget to take a tablet in time. Not had a migraine for years - i feel utterly exhausted.
