I am 51 yrs. All my life, my bp has been almost consistently 120/80. Recently, during a period of high stress and anxiety it shot up to 140/100. After a few days at that level doctor put me on concor 2.5. Two months later it was consistently dow to 110/75 or 115/80. Last visit he measued 120/70. He reduced dose to 1.25 . Its been a week and now readings are 120/85 to 130/90. Can I expect it to gradually come to normal without meds?
