I've just come home from a drive with my family and I noticed that when we arrived home, a weird "pressing" sensation occupied the left side of the back of my neck, leading up to the left side of my head, giving me a headache and making me feel slightly nauseated.
I'm a 17 year old girl with no past brain injuries or any serious medical problems almost EVER! I've always been rather healthy, so this is a little worrying as I've never felt like this before.
