Strange pain when I bend forward
I exerted myslef yesterday and at the same time felt something 'go' in my head. Since then I get a pain when I bend forward and it feels like I'm going to have a nose bleed. I also get the sensation when lying in bed in one position for a while at the point I turn over.
It also feels like there's liquid in my head that is flowing to the lowest point whenever I move.
When I'm standing, walking and even running I don't get the problem.
I've never head a headache in my life and am very healthy and very fit. Resting heard rate is < 40 and bloos pressure 110/60.
I thought it might go away overnight but it hasn't.
