How about checking for "Hypoglycemia, or Hyperglycemia" , either way this, this is low blood sugar, from diabetes. I have fainted about 4 to 5 times in my life time since I was 25 now I'm 43 and watch and control mine with diet alone and check my sugar.Once at my work they called the ambulance and my sugar was down to 32 and I was better later in the hospital but I had most of those same symptoms, numbing of hands and feet, cold chills, then hot sweats and real dizzy, and depressed, crying, and finally I guess I passed out. Good Luck perhaps?
