50yo F, has fibromyalgia. Bloodwork for unrelated shows anemic, so my doc prescribed iron 325mg, 2x daily. I m taking one tablet, every other day, because I developed don t-leave-the-house diarrhea, chills, sweats, no fever, pruritus and severe exhaustion. 2-3 naps a day exhaustion. Could iron be a cause of any or all of this?
