Hello - I'd have a look at Hypopara.org.uk - there is tons of info on there about parathyroid issues (and not just hypo). Thyroid and parathyroid issues can be related (e.g. many people have para issues after thyroid surgery) but tests and diagnosis and treatment are different altogether, so thyroid tests won't tell you what your parathyroids are doing.
Have you had a parathyroid blood test done at the same time as calcium ? If your parathyroid is normal then other reasons for hypercalcemia must be looked at. It is never good to have high calcium as it causes many other issues. Have a look at hyperparathyroid.org.uk for lots of info.
VitK2 MK7 is supplemented to encourage calcium away from the arteries and soft tissues into the bones and teeth. This is normally suggested on the Forum when people are taking high levels of VitD. Just wondered if it would be helpful for you too ....
