Fatigue was attributed to fever rather than vitamin B12 deficiency

The observation separates low energy from presumed vitamin deficiency and places the immediate explanation in the context of fever.

The symptoms did not point clearly to B12 deficiency

The reported pattern was low energy, feeling less energetic overall, and tiring easily. These symptoms were initially linked to a possible vitamin deficiency, with tablets suggested on that basis.

However, the current impression was that vitamin B12 was not needed. The fatigue seemed more likely to be related to the fever.

Fever became the working explanation

The recommendation was to proceed with Dolo 650 for now, described as the best immediate choice in the current situation.

The question is whether the low energy resolves with the fever, before pursuing a separate explanation for fatigue.
