I recently temporarily lost some vision in my right eye. I also felt sick and weak when it happened. I went to er and was diagnosed with amourosis and probable blood clot. I was in hospital for two days. They did cat scan of head, neck and didn t find anything showing wrong. Since I ve left the hospital I now have a,whooshing sound in my left ear that seems to go with my heartbeat and doesn t go away. I m concerned as I read this can indicate a vascular problem or dissection. They did a ct scan with contrast to check and told me it was normal and I should see an ent. Advice?
