When experiencing pain on the right crown of the head

I've been experiencing persistent pain on the top right of my head for several weeks, and it's really bothering meㅠㅠ

At first, it felt mild, but recently it has been getting worse.

It feels especially more noticeable when applying pressure or sitting on the toilet for a long time.

This pain sometimes causes a stabbing sensation like a seizure, and other times it feels dull, interfering with daily life.

It even often makes me wake up during sleep.

I want to know what causes these symptoms and how to respond in such cases.

I'm also curious about self-care or treatment methods I can do myself.

I would really appreciate it if you could share expert advice or experiences regarding this situation.

I am experiencing significant worry and anxiety, and I would like some advice.

Thank you to everyone who left comments in advanceㅠㅠ
