Could this be a vitamin D issue or is this the onset of a kidney disease?

I was in a good shape for the holidays this winter.

In early January I had a nasty E. coli bladder infection that was treated with two rounds of antibiotics (a unidose – which didn’t work – and a 6 day course). It was really bad, even if when it cleared up, I still had some discomfort (feeling my bladder was somehow « distended »).

I started getting tired easily, sleeping badly .. . so my doctor did a routine bloodwrok and checked my thyroid (I already have Hashimoto’s) and parathyroid.

My parathyroid hormone is high.

Potassium is high (calcium is normal and so is sodium).

Kidney function is lower than usual (CKD EPI 80; it’s usually around 100 / Creatinine is normal but getting higher).

I thought that my joint pain was from arthritis (Ankylosing spondylitis).

My left kidney hurts. It’s been hurting on and off for the past three years but they said it was probably kidney stones (which they found in the right one not the left, but hey).

What should I do while I wait for the results (my doctor repeated sole old tests and order new ones)? Any foods to avoid, any foods to include into my diet? Should I continue drinking green tea? It’s diuretic. Basically, how do I help my kidneys?

Could this be caused by a lack of vitamin D?

I don’t want to worry, but, worry I do, a bit.

Thank you.
