I get back inside, what do I do?

I've had a strange headache since this morning.

But since I was / am on the laptop because of homeschooling and somehow held my head incorrectly, the headache feels like this:

Throbbing headache
"Drowsiness"
Pressure headache
fatigue

But other things like:

Feeling of "tipping over"
When I turn my head, it feels like everything "arrives" seconds later
Neck pain
Jaw pain
heartburn

In summary, I'm very afraid that it is something bad like a brain tumor or something, because I can already see that the headaches are different.

Even when I look at the screen of my laptop or cell phone, I feel like I'm sick or dizzy.

I'm really panic and scared right now

Nobody here will be able to give you a diagnosis just go to the hospital or call an ambulance service, not that it's worse.

Get well soon, I wish you the best

Maybe it's because of the weather change… But it could also just be migraine. I wouldn't worry much. Relax and take it easy. Drink a lot. If the pain persists and you seriously think it's serious, you can still go to the hospital and have it checked out.

If you have the feeling that you are going to tip over, you should see a doctor
