  • Hi no one on here can diagnose you and you need to see your doctor if you are worried. Do you suffer from asthma? x

  • Google:- AMAUROSIS FUGAX

    (transient monocular or binocular visual loss).

  • High there, that sounds like a low blood pressure thing, often occurs with relatively tall people I think, and more in one's youth, I had the same.

    Is there also a feeling of 'becoming distant from things'? - a sort of feeling as though you might collapse or faint? That's what I had. However, it's worth mentioning it to a doc in case it's a sign of something else, or indeed if your blood pressure isn't working like it should.

  • This can have a variety of causes. Only a doctor can do or arrange the tests to determine what the problem is.

    One cause can be serious, another cause could be minor one easily fixed.

  • I used to get like this. It was down to low blood pressure. Make sure you aren't cutting out too much salt in your diet. When my kids were babies I didn't cook with salt and I found I was worse. When I added a bit if salt occasionally the symptoms improved. If you are worried, speak to your doctor.

  • I don't usually have water that often that much
