ombowstring..There is an inverse relationship between The Parathyroid Level and The Vit D level..!!!
I kinda agree with your Physician..That your Parathyroid Adenoma should be removed..A level of 13 on your calcium..Would land you in my ICU..No kidding..Please be careful of your kidney and Heart function..I’m sure your Physician is watching them closely..!!!
I’m afraid I have not been of much help to you..I understand your reluctance to go under the knife..During Covid..BUT.. Please be careful..!!!
