Lithium Carbonate and calcium

My joints all over my body are painful. I don not know if it is a side effect of lithium because I take other medications. The drugs include femara, niravam, cymbalta, famvir, calcium 1000 mg., a multivitamin capsule, glucousimine, echinacea. please give me some advise as to why I get veryt painful joints and the back of my neck pops constantly throughout the day.

I take Lithium and I have a high about of calcium in my blood. Does Lithium cause that. I just had a test on my parathyroid glands but don't know the results. Please tell me about the high calcium when you take Lithium I take one pill a day at 300mg., I think.

Thank you,

Rae ***
