I have been feeling sick since July of last year. About a year and a half ago I passed out and fell down 3 stairs and landed on my head. Doctor said I had a concussion. In July I felt like the same thing was going to happen and the feeling has never gone away. I'm dizzy, nauseous, thirsty, extreme migraines, extreme motion sickness, and lots of loud ringing in my ears. My doctor did an allergy test And I am allergic to stuff but have stayed away from them since October when I was diagnosed. Please help me I don't know what to do anymore. Nothing is getting better. I have had a ct scan and an MRI and both came back normal.
