hi sue
I didnt have an SCT as my kidneys were damaged PP do fluctuate a bit so dont get worred yet as for calcium I have pamidrinate once a month because i cannot had Zometa which is bad for the kidneys which some times takes my calcium to low so they give me a suppliment just to boost it up a bit to low calcium can give you the shakes and cramps so you can have calcium now and again good luck with your treatments
