head
 

This is probably sound odd but hey. I woke up this morning with a headache that hasn't gone away. Anyway just now I'd gone into the kitchen and suddnely my head was really painful. To the extent that i had to lean on something to keep my balance and my vision went all blurry. It passed withing a few minutes but then came back again around a few minutes after.
Does anyone know why this could happen?

possibly dehydration-make sure you drinkiing lots of water.

speak to gp/ walk in centre if doesnt improve x

As mentioned above, it could be dehydration. This usually makes you have a bit of a headache , you usually feel dizzy, weak, and tired too. It can also be stress which is one of the major causes of headaches. Tight muscles in your neck can also cause it. Heaches are actually a symptom of a lot of things so if it doesn't start easing off then go and see your GP. Ibuprofen and Paracetamol are good for headaches so it may be a good idea to try taking those see if it helps. Sitting down, relaxing and drinking plenty of water are probably even better things than just taking tablets to as they might be able to alleviate the cause. Try to stay away from Caffiene too as these can cause it. Sleeping may also help as you can get headaches from not enough sleep. If bright lights make it worse/ your vision starts going funny it might be an idea to go and lay down in a darkened, quiet room to stop it worsening and try and ease it.

Televisions and Computer screens often worsen headaches too.

it could be a problem with blood pressure as well. i had a lot of those headaches when i was pregnant and i had BP issues then.
