Recheck calcium. First re-check your calcium level to exclude lab error then if it remains high consider having your parathyroid hormone checked (PTH) by your provider . Pth excess causes your body to inappropriately remove calcium from the bones causing 'hypercalcemia' . At first there may be no symptoms but if left untreated multiple symptoms abound.
Revisit lab and doc. High calcium can be from high parathyroid hormone, excess vitamin d, (sarcoidosis and other diseases increase vit d) excess ca intake and lab errors. This should be checked again with an ionized calcium, total calcium, vitamin d level and a pth. Physician interpretation will be needed.
