Epidural side effects

We were just discharged today and I woke up to pee and got some pain and lost some sight in my eye (like when someone takes a picture with flash). Now let me say this has happened before. My blood pressure gets low and I believe that's what happens because I also feel shaky when it happens but it hasn't helped since I found out I was pregnant. Should I call doc in the morning? Sight came back like it usually does
