Have you checked fever?
What is the nature of headache?
Like throbbing,constant ,stabbing or what?
Is there eyes swelling?
Have you ever experienced such pain before ?Is this sharp and severe?
In light of all this I will suggest you to see your primary care physician for an examination.I do not want to scare you but better to get examined and get timely treatment.
Nature of pain along with eye swelling is not a good sign.
3o % chance is that it is thrombosis pain.
However,a cluster headache do present in the same manner.
But cluster headache is a benign headache.
But it was swollen before....so cannot ignore it.
It is not very common .It happen only in 5 % of people but who knows if you are in those unlucky few.
But first take 2 Aleve.
If pain settle up with Aleve or Panadol then
and does not come back ,its not thrombosis.
Thrombosis pain main feature is that it does not go away easily.
It should come back within 24 hours to be a thrombosis .
Thrombosis pain is hard to handle and it takes his patient forcefully to ER.You cannot tolerate it.
Wish you good health.
blurring of vision or any other eye changes ,dizziness etc.
Can happen with thrombosis .Some time fever as well.Some time a bad headache is only feature.
First take a pain killer.No need to worry.You can go to ER directly.
Hopefully ,it will settle after pain killer.
Give it atleast 3 to 4 hours.Take rest by curtains down.No computer ,no TV ,no phones etc.
