Hello,
I felt a bit 'soft' posting this in this section but oh well.
I've had a constant, really banging headache for 8 days in a row now. I've very painful and feels like it's all over rather than in a direct place.
I've sustained no physical injuries to the head, I don't think it's eye-related (e.g. staring at a screen or squinting). It's also not down to dehydration as I drink a lot of water regularly to flush my system out.
So what could it be? What's the usual cause?
Thanks.
