The pain is sharp and it feels like a nail going through my head. I went to the dr they cant seem to figure out the problem. But the dr did say my blood pressure is boarder line high. I have never had high blood pressure before. How can these to be relatead so i can figure out what is wrong with me. because this headache simply wont go away!

• Answer:

  Headache is generally regarded as being a symptom of high blood pressure, although it is also stated that hypertension is the “silent killer”. Many people who have high blood pressure think that when they get a headache it means that their pressure has gone up. The problem here is that both headache and high blood pressure are very common, which means that it is certainly true that the two occur together, but what exactly is the connection. "My best guess is that higher blood pressure does cause headache -- but that is a guess," MD Law tells . "We can't exactly shout from the rooftops that high blood pressure causes headache, although we think it probably does."
