Out of the blue got a headache last night, it came on quite suddenly. The pain is throbbing and sort of behind my left temple / eye socket but it moves a bit.
Carried on all night, but I did get some sleep. It seemed a little better during the day and I was able to get about and do stuff. Just got home and it's throbbing again. Cocodamol hasn't touched it.
What can I do?
