The elevated calcium could indicate a problem with the parathyroid gland. There is a blood test for that, so I'm sure your physician will test for it.
My other thought here, though is water. Elevated albumin, muscles twitches, strong smelling urine, tired, trouble concentrating---all of this can be due to dehydration. Before anything else, take a look at what you actually drink in a day. Do not count beverages with caffeine as these can be diuretic, causing you to excrete more water. And is you drink soda pop---Stop. Drink more clear liquids without caffeine, and more water. You need at least 2 quarts of water daily. More if you perspire heavily, or if you exercise alot.
Having said all that---elevated calcium is never normal. There is something causing it, so be sure to follow up with your physician. Hyperparathyroidism is the most common cause, but there are other conditions as well: cancer, sarcoidosis (body's immune system is overly activated), excessive vitamin D intake, to name some.
And it is possible for your symptoms to be caused by hyperparathyroidism. Here is a link for more information about this disorder: Mayo Clinic's page on Hyperparathyroidism
