On Thursday night I had a bit of a headache and general muscle ache this carried on until Friday night when the pain got so bad that I couldn't sleep. Spent all of Saturday in bed or bent over the loo. Moving, light and loud noises all made the pain worse. I stopped feeling so sick on Saturday night but headache was still going strong. It has been fading all day and now I feel OK. Was this a migrane or just a bug or something else?
