I feel and hear clicking in my head, like small parts rearranging themselves inside my skull Especially when walking, or staying with my head upside down.
When I click I also feel a compression in my headspace, like something pressed it within from all directions, but this also happens without the clicking. I sometimes feel my head pulsating, it hurts when I focus on it.
I must say I'm young and with no neurological history. The only causes I can think of are the following :
Some weeks ago I went outside for 5 minutes before travelling by car after I had washed my hair and air dried. My head hurt for a day. That same day I drank some liquor (the hurt aggravated) and accidentally hit my head to a bed. But since then, these issues stayed. I don't think a mere drink or hit can cause week lasting issues.
