Hi hope somebody can help ! always fit and healthy normally, was out running last year and became dizzy unbalanced had ct scan / mri / nothing showing i now have been told it could be a occipital nerve problem as i have a feeling of a full ear?

Ear problems: Sorry to hear that, I am not sure if you had your ears checked by an ENT. Inner/middle ear problems can be a common cause of unsteadiness and dizziness in otherwise healthy people especially if positional changes trigger it. Other signs to look out for that may happen are decreased hearing and ringing in the ears. Occipital nerve or cervical causes are less common. Hope this helps.
