I have had major swelling and headaches and lately i've been getting the black spots in my sight, but each time the doc checks me my bp is normal and urine is fine. They keep telling me as soon as it happens get straight to the doc/hosp but by time i get there my sight and or headache will be better or gone. I can't get there quick enough. Can these just be symptons of something else? I asked the doctors + midwives but they didn't have an answer and just keep telling me to come back in. I live 30mins from the doc and 45mins from the hospital and i don't always have transport. Should i be concerned?
