Hi there, and welcome back. This is Kitt.
I was so glad to hear you were taking the "bull by the horns". Your Pdoc should be able to suggest a good medical physician for you. You may want to try an Internal Med physician. Internal Med physicians are trained to solve puzzling diagnostic problems and handle severe chronic illnesses and situations where several different illnesses may strike at the same time. They also bring to patients an understanding of preventative medicine, men's and women's health, substance abuse, mental health, as well as effective treatment of common problems of the eyes, ears, skin, nervous system and reproductive organs. Most older adults in the United States see an internist as their primary physician. I am not sure of your age but with the high BP and being on Toprolol an Internal Med Physician may be the way to go.
You will need your Pdoc too. Please remember that if you feel like your going to faint, speak up, it is always nice to know when a patient is not feeling well and you may lay down. This is a very common problem for many so you are normal as far as fear of the Doctors office.
Keep posting and glad to have you back.
