This seems more like an issue where the Dr was giving you correct advice but you weren't hearing what you wanted to hear?

Why would you infuriated by a Dr telling you to go outside more to increase Vitamin? That's exactly what they should be suggesting in the first instance.

Well, first of all it is early march and the sun is at an too low angle.

Secondly I working from home for over 2 years now, and during most months of the year it is already dark outside when I am done with work.

Thirdly, I already have symptoms which correlate to a deficit, so the doctor not even wanting to look into it baffled me. And well, I never managed to talk to a doctor with my actual test results, but from looking at papers/official resources, 4ng/ml seems to be extremely low as a vitamin d level.

Well in the end I obviously don't know if those symptoms are the result of my vitamin d deficit, but time will tell.
