for about two year now, sometimes i feel cold and at the time i can feel my body is heating up. it goes on from 1 hr to 12 hrs. my primary doctor thinks that i have low body temperature. so i am more senistive to the cold. i just don't know what it is.

does anyone hear of this or experienced this type of problem.

Get your thyroid checked. Hypothyroidism can cause cold intolerance. It's a simple blood test.
