luvmarypoppins: the change in your TSH is fairly minor. It is a change and could be indicative just anything. However, most non-thyroid cancer people, are normally at 2.0 and that is considered the "ideal" TSH. At .86, you are not considered hyperthyroid and this number would not make you tired. I don't know your age, but I know you have college aged kids and I'd be more inclined to think you have perimenopause or hormonal issues than TSH issues. I don't sleep more than 5 hours a night most nights anymore due to this an am always lethargic. But my 40/50-ish ladies around me are all feeling the same way. As for the calcium, that is something that can flucuate daily so I'm not sure what to make of that, if anything.
