Hie, for the past 2 weeks i have had this heavy headed feeling, sometimes at the back of my head, sometimes it feels like the whole head. The feeling will be there constantly. Throughout the day, sometimes i feel throbbing pain at both sides of my temple. Apart from that, my eyes focus seems to be getting weird - don't really know how to explain the feeling, but it feels like my focus expands and then shrinks. My eyes also feels tired easily since this whole episode started. Before this happens, i've had a few other worries regarding my health, and hav been getting up several hours before i am suppose to be up. I have done a renal blood test (the doctor thought i might be anaemic) and a CT scan, both of which came back negative. I've been asked to go to an eye doctor instead. Should i be worried about brain tumour? last few months i have lost 5-8 kgs voluntarliy but now i feel i should not have. may be thats the reason, but i need advice thanks
