Why would I have high calcium levels?

[Jubi5101]

So a little back story, the past couple years I have been very sick. I have fatigue, nerve pain, muscle pain, bone pain, frequent urination, insomnia etc. I was originally diagnosed with Fibromyalgia, but I feel that it is something else. Last month I had my calcium levels taken, and I had an 11.1(10.5 normal). My doctor ordered tests to see if I could have hyperparathyroidism, but she told me that my PH levels are normal, and that my calcium went down to 10.6(still slightly elevated). She told me that it is nothing to worry about, but I feel like maybe this is the key to everything. Most days I feel like I am dying, and I worry that I could have cancer. She dismisses that though, because my white blood cells are normal, although my red blood cells are slightly elevated. Does anyone have any idea what this could be?

Please post the actual serum calcium and PTH values when taken at same time. Also please do 25-hydroxy Vitamin D3 test.

Also if want to know the reason for high calcium do these basic tests too.
Serum Calcium
Serum Phosphorus
Alkaline Phosphate (to know if bone modification taking place)
Serum creatinine (to rule out kidney problem)
Free T4, Free T3 and TSH (to rule out thyrotoxicosis induced hypercalcemia)
