Should I tip my head back?
No — lean forwards. Tipping back sends blood into the throat and stomach, which causes nausea and vomiting, and makes it impossible to judge how much you have lost.
It is the most widespread piece of wrong first aid there is.
How long should I pinch for?
Ten minutes without releasing. Letting go at three minutes to see whether it has stopped is why bleeding restarts.
Time it rather than guessing.
When do I need A&E?
If bleeding continues beyond 20 to 30 minutes of correct pressure, if it is heavy enough to make you feel faint, if it follows a significant head injury, or if you are taking an anticoagulant and cannot stop it.
Blood running down the back of the throat rather than out of the nostril also needs assessment.
I am on a blood thinner — does that change things?
It makes bleeding harder to stop and lowers the threshold for getting help.
Do not stop the medication on your own. Stopping anticoagulation carries its own risks, and the right approach is to be reviewed rather than to make that decision alone.
My child gets them often — is that a problem?
Usually not. Nosebleeds are common in children, typically come from the front of the nose, and generally settle with age.
Worth reviewing if they are frequent, heavy, or come with easy bruising or bleeding elsewhere.
It is always the same nostril. Does that matter?
In a child, usually not — it is a prominent vessel.
In an adult, repeated bleeding from one side is worth an ENT look, particularly alongside a persistently blocked nose, facial numbness or hearing change.
Could my nasal spray be causing it?
Very possibly, and it is one of the easiest things to fix. Steroid sprays aimed straight up at the septum irritate exactly the area that bleeds.
Aim outwards towards the ear on the same side, using the opposite hand.
Does high blood pressure cause nosebleeds?
The link is weaker than most people assume. High blood pressure can make a bleed harder to stop, but it is rarely the cause.
It is still worth having checked, since it is often the first time anyone measures it.
Can they be cured?
Often, yes. Where a single visible vessel is responsible, cautery in an ENT clinic is quick and frequently ends years of recurrence.
