Hi
Sorry I cant help with actual symptoms after chemo etc.
I do hope you are recovering well.
I do know that Calcium is made by the Parathyroid gland (part of/next to thyroid gland) and when not functioning properly can make too much calcium.
My aunt has too much calcium due to this & has to avoid all dairy products especailly all milk..even soya,goats etc. She is tested regular to make sure it doesnt get out of control.
Ask your doc to explain what is making you have too much Calcium.
I wish you well and hope you find out why this has happened to you
