Feeling pressure in eyes under eyes. sensitive to light dizzy feeling as well. i feel this daily and then i get anxious. is this a sign of tumor?

Unlikely tumor: There are many many causes for pressure under eyes and light sensitivity. Unlikely to be a brain tumor. You should see your primary care doctor though for a careful neurological physical examination. And if the symptoms persist for a month a brain MRI is probably warranted at that point. But try to see your doctor before then it's better.
