All tests indicate that I have a tumor on one of my parathyroid glands. This causes very high calcium levels, which can cause headaches (as one symptom) and my dr. says he's seen people be diagnosed as clinically crazy from the high calcium levels (where their calcium levels were lower than mine!). I am waiting for a referral to a surgeon who can 1) give me a 2nd opinion and 2) get rid of it. I mostly need prayers for patience.
