I have constant migraines, often dizzy, my ears ring and lack of appetite. Are those symptoms associated with anything specific?

Perhaps. These can be signs of underlying disease in the brain including tumors. You really need to see your medical doctor and a neurologist.
Migraines? Any headache must be viewed as a valid medical disorder and the headache assessment must be comprehensive. Secondary or organic cause must be ruled out. Once a diagnosis of migraine has been made, effective management of migraine should be applied.
Migraines. Could be related to your migraines. Dizziness and ringing in ears is not uncommon. See a neurologist to seek treatment.
