question: Hi doctor, I had a baby 9 months ago. Since I was 18 weeks pregnant, I had heart palpitations and high blood pressure. I do not have high blood pressure now, but I am still having palpitations, but not as frequent. It seems to be a hormone imbalance. I got them this month on the first day of my period and a couple other random times. Two weeks ago, I started getting swelling in my right hand only when I lie down or sleep. Also, I have had random itchy spots like hives just in random places.
