Hi all,

Lately I have noticed a dizzyness/drug type (best I can describe it) head spin whenever I shift my head position say from normal standing position to laying down and looking towards the rear and vice versa. It sometimes occurrs when rising from seated but is far more prominent in the situations as described above. I feel a bit "stoned" for a few seconds and then I normalise.

Can anyone shed any light on what this may be. I am 57 and very fit. 180cm, 78kg and run 5kms 5 days a week and add strength work in during the runs. I feel really good and have no symptoms when under full exertion.

Thanks. Grahame P.
