Greetings! I am ma.theresa,age 43 I would like to know if what are the probable causes of sudden dizziness with cold sweat, feeling of vomiting and lost of vision. . . I just experienced it today at around 10 am and it got started of an upset stomach and/ir abdominal pain. I am in kitchen when it happens, so I suspect some kind of a poisoning from gas stove range??? This isn t the first time,it was the 2nd time now as far as I remember and the first time it was happened, I was over at kitchen also. I almost collapse while inside rest room! I m getting worried and I need a conclusions in regarding to all this. . . Thank you very much and good day!
