I have had a headache for 12 days now - it is a dull ache around my forehead which every now and then intensifies to a sharp pain, and sometimes goes into a migraine (i get these occasionally). I have also been feeling a bit sick. It's distracting when i'm driving - it makes my eyesight a bit strange (can't really explain how, just not quite right).
I'm not dehydrated, under more stress than usual or sleeping any differently, and my blood pressure is fine.
I saw the GP yesterday and he checked my eyesight and gave me codeine and paracetamol tablets (they are quite strong). They take away the headache but not the stuffy head feeling or eyesight strangeness, and they do make me drowsy.
I have only taken painkillers when absolutely necessary as i know taking them too often can make it worse.
Any ideas? I'm not really happy with taking loads of painkillers without knowing any underlying possible cause.
Thanks
