How can I differentiate thunderclap headache vs dehydration?

So first off I’m a Nurse myself so I feel so stupid but I have a bit of anxiety as my mum died of a sudden brain haemorrhage after high blood pressure and headaches at 57 two years ago.

I’ve been away with my sister so lots of walking and probably not enough drinking so I’m inclined to think it’s probably dehydration but I woke up at 2am last night in the hotel with the worst headache I’ve ever had right at the front of my head. Think clutching head and groaning. I scrambled to find some paracetamol and slept but over the last 2 days I have felt a bit odd in general like very hot and headachey. Also still feel headachey today and if I cough my head hurts. I know I’ll probably get told to get checked but I can’t help feeling like they’ll think I’m anxious or what is she here for ☹️ I think probably it’s just dehydration but there’s just the worry because of what happened to my mum so young, she also had a cousin that also died of brain haemorrhage

drink something - if it gets better it was dehydration. Clearly with your family history you need to get real life medical advice today if it hasn't got better.

Tried to increase fluids today and still feel hot and headachey so guess I better take myself off to a&e 😖 just working in a hospital really makes you second guess going sometimes because you don’t want to be a bother but then know in yourself that the patients that don’t want to bother anyone are normally the ones that should have. Thanks for the kick up the bum
