<s>[INST] I have been diagnosed with having a shadow on the left side of my brian having suffered severe headaches for many years . (I am right side haemoplegia). I at present when move quickly go dizzy or when lying down and et up quickly or just turn my head or whole body to the left I got extremely dizzy. Is this a sympton of the shadow or am i suffering from vertigo . Alternatively, have I been diagnosed wrong after my scan and i have a tumor as original when diagnosed i was told by my optician that i had the symptons of a brian tumor and that is why i had the scan in the first place. Can you give me a clear answer please. thank [/INST] People that suffer from headache for many years are predisposed for brain injury.Brain tumors does not cause acute haemoplegia. The symptoms that you are suffering from seems to be related to vertigo. I will be more sure about my answer if you could sent me the exact result of the CT scan. Wish you all the best </s>
