Gait and balance: Gait and balance rely on proper functioning of the eyes,ears,brain and muscles. See a neurologist for evaluation

Ent and neurology: There are many causes of dizziness. You should have a vng and/or mri with blood work and possibly a hearing test. If you already had a ct, was it of the temporal bone? One possible reason for your stmptoms may be superior canal dehiscence but you should probably see an ent.this diagnosis would require a fine cut ct of the temporal bones.
