I'm afraid i have a brain tumor. could dizziness and nausea from a brain tumor get better over time. i now have headaches with little nausea?

See a doctor: Unlikely you have a brain tumor based on your symptoms but if you have any concern, you should get seen.

Brain tumor: Say tumor & brain, yikes! who isn't terrified?Important to ask is why do you think you have one? (very legitimate, valid reasons no doubt. I'm not disregarding!) have u had a tumor? Imaging of brain? Family history? Yes, can cause n, v, & ha, but also 5000 other things (most more benign luckily.) am headache worse w valsalva poss. Please! talk to your doc about ur concerns. They can help!
