I had to have a D&C after a missed miscarriage 3 weeks ago. Since then I started having headaches, dizziness, and nausea. I was fine until after my 2 week f/u. it started about 4 or5 days age. I currently have a headach that has been on going for 3 days. This morning I woke up so dizzy I could not stand. I have not been able to eat or be exposed to noise, or light with out getting really dizzy, and sick. I actually vomited today from this. SHould I seek medical attention, if so at what point?
