Ferritin, iron studies and the fatigue question

Ferritin, iron studies and the fatigue question — putting it in its own thread so it does not get lost in the check-in.

Evidence question. I would rather have an honest "we do not know" than a confident answer.

I am aware some of this may be nothing. I would still like to know whether other people have had it, because I have spent a fortnight assuming I am the only one.

Here is where I am. The medication side has been more or less as described, and the part nobody prepared me for is everything around it: what to say to people, how to plan a week, and how to tell the difference between a thing to endure and a thing to raise.

Sorry for the length. If anyone has been here, I would very much like to hear it.
