These aren't so weird. Hypocalcemia is a deficiency of serum calcium, the calcium in circulating blood. It could account for the muscle pain. Lymphocytopenia is a decreased number of lymphocytes, a white cell that makes up about 25% (15% to 40%) of our total white count. A deficiency is associated with nutritional deficiency, malignancy, infection and mono to name a few.
Now, the parathyroids secrete a hormone that regulates the concentration of calcium in the blood amd also ensures normal neuromuscular irritability. Acute parathyroid malfunction (hypoparathyroidsim) results in tetany (cramps, twitching and severe muscle spasms) and you're not having that so yours, if you have it, may be mild at this point. This condition can also be asymptomatic.
It could still be a parathyroid issue and your doctor may have ordered a serum phosphate (phosporus) along with the calcium. In hypoparathyroidism, decreased calcium will be accompanied by increased phosphate. Was a urine calcium also done? How about a CT? I'm trying not to zero in on any one thing just yet. I feel that the additional labs you're waiting for will be helpful. Is there any way I can follow this?
