A friend of mine has had a headache constantly for 2 weeks. He has tried all the usual painkillers and they haven't done more than touch the edges. He was diagnosed with high blood pressure a wee while ago and is on medication for that but still the headache persists. he is about 40 - anyone any suggestions other than telling him to go to the docs??
If the cause of headaches is carbon monoxide poisoning, a carbon monoxide detector is cheap and will beep if carbon monoxide is present. Note that when the batteries are low, the device also bleeps.
thanks sqad - he normally lives down south and was up in scotland for a few days and he flew up so would guess that it cant be the car or the environment unless the symptoms persist? Hope he gets to GP soon.
