I understand that the OP is asking how to lower blood pressure before going to see a doctor. So, even though telling her to see one is good, it doesn´t answer her question. I am in much the same position, hate going to the doctor, hate being on any medication long term, am quite a nervous person though and my BP always goes sky high when measured by a doctor. There are lots of things you can do to lower blood pressure naturally and there are lots of useful hints on youtube and elsewhere on the internet. Changing diet is the most important, avoid processed foods for a start, if it´s not found in nature, then don´t eat it. Cut down on or avoid alcohol, caffeine, sugar and wheat. Things that are known to lower bloodpressure are garlic, chilli, ginger, leeks, onions, parsley, citrus fruits and many others. Making a clear vegetable broth from various root vegetables (as well as leek, onion, garlic and parsley) and drinking this regularly has helped me a lot. Drinking the juice of a lime diluted with water can lower BP quite quickly. Breathing exercises are also useful, basically, whenever you can, while walking or watching television make a conscious effort to breathe deeply and slowly, after a while it will become a habit. Hope this helps a bit, don´t underestimate seeing a doctor though.
