In 2024, there were 3.1 million days lost through sickness absence where the reason given was ‘headaches or migraines’. However, there are some signs and symptoms accompanying a migraine that indicates it may need more than a sick day in bed to record from. Migraines can trigger some symptoms known as an aura, these may be warning signs that the migraine is about to start. It is also possible to get these aura symptoms without experiencing an actual headache, this is known as a silent migraine. The NHS recommends keeping a migraine diary which may be able to pinpoint any common factors during migraines that could be your triggers.
