Having Headache, Anxiety, Feeling Nauseous And Dizziness. Could It Be Brain Tumor?
Welcome to Health Care Magic
It is not easy to conclude or exclude any particular diagnosis from your description.
Anxiety can cause headache / headache can cause anxiety – it is a vicious cycle. [Probably anxiety could account for the whole picture – but it should be an exclusion diagnosis]
Nausea could be from dizziness / dizziness primarily points to the ear as the cause. [There are other causes like blood pressure, anaemia and so on]
As a general rule, symptoms lasting more than a month must be investigated.
You should seek Neurological consultation.
The best solution in this situation is to have MRI (and/or MRA) for the brain.
That is the only and sure way to exclude tumour.
Take care
Wishing speedy recovery
God bless
Good luck
