Brain tumour? or something minor..please help!!?

Try having your blood pressure checked. I had pretty much the same symptoms. My head hurt as if a knife was stabbing me from my eye through the back of my head. My blood pressure was high so they put me on BP medication. The headaches and other symptoms want away immediatly.. Your problem may be as simple as that. I have to take medication every day but it's no big deal. So relax. Your stressing out about it is only making it worse.
