Headaches are super common and can feel really different depending on what's causing them. Here are a few types and some signs to look out for that might mean you need to see a doctor:

1. Tension Headaches: These are the most usual ones. They usually feel like a tight band around your head and are often caused by stress or sitting in a weird position for too long.

2. Migraines: These are a lot more than just a headache. They're intense and usually come with nausea, sensitivity to light or sound, and sometimes even seeing weird stuff before the headache starts.

3. Cluster Headaches: These are super painful and happen in bursts. They often come with a really red eye and a runny nose on one side of your face.

4. Sinus Headaches: If you feel a lot of pressure in your forehead, cheeks, or nose, it might be a sinus headache. These happen when your sinuses get all swollen and irritated.

Now, if your headache comes with any of these signs, you should definitely get it checked out:

• If it starts really suddenly and is the worst headache you've ever had or can imagine.

• If it comes with things like weakness, numbness, or trouble talking.

• If you've had a recent head injury.

• If you're over 50 and your headaches are getting worse.

• If you have a fever, stiff neck, confusion, or seizures with your headache.

These signs could mean something more serious is going on, so it's better to be safe and see a doctor if you're not sure. You can call NHS 111 for free to arrange a callback from a Paramedic, Nurse or Doctor. The healthcare professional will be able to ask more questions and advise whether further tests are required.
