For a few weeks now i've been getting dizzy spells and just generally feel light-headed most of the time. At my last check up my BP was 100/70, normally it's 120/70 so that's pretty low for me. Is there anything i can do to stop this light headedness feeling? I get all cold and it feels like the blood is just running out of my head, down my body and feel nausous and then sometimes have blurred vision and my hearing goes. I don't have another appt for 3 weeks. I just don't know what to do, it's affecting me heaps and making me feel really tired and worn out, without me having to do anything.
