So I've been waking up gasping for air in middle of night, once I'm up I notice my vision is blurred, seeing stars, heart pounding and slight headache. My throat/neck is stiff and standing and walking doesn't help. Not to mention way too dizzy to walk. I usually have low blood pressure, but they don't tell me what it is when they check. Does this sound like preeclampsia or something else you know of that I can ask doctor about?
