Have you ever had your thyroid tested? it's a pretty simple blood test that your doctor can do to determine if there is a problem. Thyroid problems can cause anything from sensitivity to cold, weight loss or gain, dry skin, about a bazillion symptoms, but the cold thing is what made me think it.
How's your blood pressure? If you are experiencing dizziness or blacking out, it could be low blood pressure, and with your cold fingers, that points to poor circulation, that could be related.
I'm not a doctor, nor do I play one on tv... But I do know that if you are experiencing something that is out of the ordinary, you should get yourself to a doctor and describe your symptoms to them.
