What Causes Recurrent Headache And Swelling In The Eyes And Legs?

I had a headache (front/middle of my head) for 3 days in a row last week. This Monday night I had horrible water retention in my ankles and calves. I woke up to a headache, this time in the back left part of my head. My eyes have been swollen every morning starting last week with the first day of headache and every morning since. Legs swollen again Tuesday night, but not as bad. Someone told me to check my Blood Pressure-I am normally 90/60 at my highest. I was 128/78 and went to a walk in clinic that night--was 124/84. They ordered fasting blood work for Wed morning. I haven t heard back yet. Just wondering possible causes.
