Hi lately I've been getting a lot of pain on my head and no it's not a migrane pain gets so bad it even effects my vision and I get nauseated and I can't afford to see a doctor I don't got health insurance and second I am scared I might have brain cancer I just don't know what I am going to do I am only 28yrs old and a single parent I'm more worried about my 4yr old son who's gonna raise him if something happens to me. Any suggestions
