calcium looks fine, but if you are still having tingling symtpoms then taking 500mg (+/-) twice a day is reasonable.
TSH is a bit low - may be appropriate if you had the surgery for thyroid cancer -- would discuss with your doctor. TSH is usually best test, but T4 and T3 can help as well in certain situations.
Oh I forgot to add that I did lose 1 parathyroid in the surgery.
