Hi I have the very same problem and don't know how to explain it to the Doctor. Seems they don't understand. When my diastolic blood pressure drops it drops fast, but it goes back up within maybe 5 minutes. I feel very, very nervous and uncomfortable when this happens. Cannot sit or stand still. Must move. Also have restless leggs . Would love an answer to help correct this. Or maybe it is not serious and so the Doctor says nothing. ThanksView Thread
