For the answer to the question above, <span>Blurred Vision

A severe headache, visual disturbances such as blurred vision and some epigastric pain that is associated with the development of severe pre-eclampsia or eclampsia. These danger signs and symptoms must be reported immediately as soon as possible. A severe headache and visual disturbances are related to severe vasoconstriction and in a severe increase in blood pressure. Epigastric pain is related to hepatic dysfunction. Ankle edema is a common thing during the third trimester of pregnancy. However, the facial edema is associated with increased fluid retention and the progression from mild to severe pre-eclampsia. Increased energy levels aren't associated with a progression of the client's pre-eclampsia or the development of the complications. In fact, some women are reporting an "energy spurt" before the onset of labor. A mild back-ache is just a common discomfort of pregnancy, unrelated to a progression of the client's pre-eclampsia. It also may be associated with bed rest when the mattress is not firm. Some multi-parous women have reported a mild backache as a sign of impending labor.</span>
