I'm a Sri Lankan. My aunt keeps me saying that she has a headache which makes her feel like a vein in her head is gonna pop. I too has experienced this situation once. When blood goes through my veins, from every pulse I get a unbearable pain in my head; I can't even think to move my body; from every footstep, it increases. Also the pain is only in the head. But it was a few minutes for me. But as she saying, this comes at least once a 3 or 4 days and it keeps going for about hours for may be a day. I have recommended her to meet a doctor, but she is insisting saying, "What if it turns out be a big one". But she is ok to come with me to meet a doctor. What should I do? What can be the reason of her illness?
