I have been suffering with a headache for about 2 weeks now constantly and it is driving me crazy, I feel dizzy and tired all the time and my vision is a bit blurred at times. I went to the chemist to ask for headache tablets and the lady said that I looked flushed in my face. She took my blood pressure 3 times and she said it was 180/130 and it was to high thats why my head is punding, it feels like it is in a vicegrip and someone is tightning it all the time. How dangerous is it someone told me it is the silent killer is that true? What tablets can I take to bring it to normal and to make my headache go away. I am so exausted at the moment it feels like I can go to bed and never wake up again. Please help me.
