I'm always cold, sometimes constipated and have already been diagnosed with cornic ear pain

It might not all be connected... however if your always cold, it might have something to do with poor circulation. I would go back and ask the dr... and if you already done that and had it shrugged off go to a different one for a second opinion if you weren't satisfied

This could be just about anything. Have you seen a Physician recently and explained these symptoms? Low blood pressure, any number of things could be involved.
