[|Human|] During the night if I turn over onto my other side I experience movement in front of eyes for about 5 secs then this stops . I sometimes have similar issues if I bend down quickly to pick something up. At these times it feels as if there is a rush of ??? inside my head which goes after a few secs. Can you help ?
[|AI|]  Hi, You may describe symptoms referable to VERTIGO and this could be caused by something such as BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV) or even something as elegant as a fistula or other type of vascular anomaly either located in or around the internal auditory canal that could then, provoke symptoms if blood pressure were to suddenly change for some reason. There also could be something in the pontocerebellar angle (PCA) such as a meningioma that might lead to these symptoms. Hope I have answered your query. Let me know if I can assist you further.
