I think it's probably normal, happens to me too and doc tells me I'm normal. What's your blood pressure?
I don't think it is normal. Because the days when I do feel normal (happens once or twice per year) it does not feel like this. And most healthy people can hang upside down without problems (at least the young), even though I can't figure out why anyone would have to;). I couldn't possibly do that more than a few seconds. Same with hand standing.
My blood pressure is normal but I have POTS so my body can not regulate it properly. When I stand up the blood rushes to my feet, so it is only logical that if I hang upside down the blood would rush to my head.
Still, not sure if it actually is the POTS or if it is the migraine..
Thank you for your answer though.
I have syringomyelia and I get this same feeling every single time I bend over. I've been told over and over by my doctor's that they don't know what it is but my syrinx wouldn't be causing it. I think that's BS cause a physical therapist I know says it's NOT normal to feel that way when bending over. I'm still looking for answers.
Did you ever find some answers?! I am dealing with the same exact thing
