mild low Phosphate/Iron IV

[Boxing]

hello all

So I had an Iron IV (first ever) on Tuesday morning and then went to the boxing club Thursday evening and literally when I finished I ended up having body aches and mild shivers felt like a flu coming on however no flu came just these body aches they have now cleared and som dizziness remains anyway I went to A&e to check it out today and they said my phosphate level is mildly low but not concerning range is (0.80–1.45 mmol/L) mine was 0.65 mmol/L. I was wondering if this is causing my symptoms? but I would assume not I think it’s what we call “iron flu” I am feeling better today no body aches or fever just slightly dizzy. I had to have the iron IV as my hemaglobin is 120 g/L (12g/dl) which is low for a man this is has now increased into normal range.

Could you please tell me is this normal reaction to Iron IV? Lastly, with kidney disease does phosphate decrease I assume it’s oposite it increases.

thanks
