Hi, I'd like to help you with your question.
What you are describing is a fear of doctors. It is called latrophobia. It is a very common fear that many people experience. Being afraid of the doctor does not mean you are afraid of the person you are seeing during your appointment. It describes being fearful of being at the doctors or at appointments.
What you can do first is acknowledge that you are afraid and that your fear is a common one. There is nothing wrong with having a fear of the doctor finding something wrong at your appointment. Most people fear hearing something is wrong. So you are very normal.
The second thing that can help is letting the doctor, or the practitioner you are seeing, know that you are fearful. That is nothing new to a doctor. Doctors are there to help but a person's health is a serious thing so doctors are used to being told their patients are afraid. Letting the doctor know will help them make you feel more comfortable. The doctor can also reassure you. And if the doctor knows you are feeling afraid, they can factor that in to your blood pressure being high. Doctors can have you take your blood pressure at home and call in the readings. That way, you are calmer and feel more in control.
The third thing to try is asking your doctor to explain things to you. It is comforting when the doctor can spell out what she is doing and explain how procedures work. That way, you don't feel that there is someone poking and prodding you and you are left in the dark as to why and what they are doing. And it gives you more control if you know the reasons behind the exams.
One of the best ways to deal with a fear or phobia is to confront it. Facing your fear is the best way to conquer it. Try working on this slowly. You can also take someone with you who can support you. Have them come in with you the first time. Then next time, have them wait in the waiting room, and on and on until you feel more comfortable.
