Girls, who have high blood pressure after childbirth? I had preeclampsia at 37 weeks, after giving birth my blood pressure didn't rise. But yesterday and today it's some kind of crap. 150/100. My head is cracking, I feel nauseous, etc. Tablets don't really knock it down, I take a little bit and then it rises again. I was in the hospital, they didn't prescribe anything decent, but tons of tests and ultrasounds, but what to normalize now is not. What do you drink? We are breastfeeding.
