What is this? Sometimes when i stand up too quickly I get light headed and my vision goes black Sometimes when i stand up too quickly I get light headed and my vision goes black but it comes back and I feel fine after a few seconds. I m tired all the time, my body aches and I ve been getting nose bleeds, but not the normal kind, It s not a heavy bleed, but when I blow my nose it s all blood in the tissue.
Hey Courtney, The light headdress is quite commonly seen in people due to a change in blood pressure that occurs from sitting to standing position. This is also called as postural hypotension / Orthostatic hypotension.  The only way to control it is not to rush from sitting to standing position. As far as nose bleed is into the picture. It seems that the blood vessels of your nose have been damaged with regular blowing. I would advise lubricating your nose with some oil - olive, coconut. And reduce the frequency of blowing to allow the injury to heal.  If still the above issue continue to bother you then you would need to visit an ENT. Hope it works, take care.  Chat Doctor.
