Sudden high blood pressure

I was up all night with the worst headache and my arms and hands going numb when I laid down. I called my doctor and they wanted me to go to L and D to be checked. My blood pressure was really high when we got there but started to come down. No protein in my urine and all my labs were normal. They are going to re check me tomorrow to make sure I'm not developing preclampsia. Any one else have a similar situation?
