White coat syndrome. This does happen to people. You should record your bp at home and discuss this with your doctor. Do you have a regular blood pressure monitor? They aren't expensive. But recording it first thing in the morning when you are relaxed is often suggested.
Having anxiety is something to 'get over'. You can discuss that as well with your doctor. Have you told them about the paralyzing fear and panic attacks over your blood pressure? Health anxiety feels terrible. I have some myself.
One of the things I do is try to keep myself in good shape. Easier said than done at times for me, I must admit but I do my best. The American Heart Association recommends at least 30 minutes of exercise that can even just be walking for 30 minutes, 5 days a week. It can be broken up into different time segments but each one must be at least 10 minutes. This is so good for heart health! Eating a healthy diet. Getting proper sleep. Those are things within your control and help with anxiety because doing them gives you some control over your health. :>))
But do talk to your doctor about the difference in readings from their office to home, your increasing fear of taking the bp in the office and how anxiety may be playing a role. good luck
how do i overcome this fear, please help me
That is a little unclear, so what is the problem; you won't go to your doctor because you are afraid of what he will find,
or
you go but spend a lot of time in fear in the days before you get in because you are worried about what the test result will be?
