Hi. Thanks for all the information. My last ferritin was 11 according to the last hematologist I saw. He never did show me any lab results on paper. This was before April 9, when I had the 2 hr. infusion of Infed. This doctor never did a ferritin test since, or any other iron levels. I felt okay for a couple of weeks, then I started going downhill pretty fast. I have been to the ER twice in the past week. I thought the sypmtoms were iron related, extreme dizziness, fatigue, brain fog. But also I've had really bad balance issues for the past few days and almost collapsed completely. Those I think are thyroid related. According to the last blood test I had, CBC, my hemaglobin is down to 11.6, and my RBC is down to 3.86. Those levels shouldn't be causing my discomfort, according to my doctors. But they did test my thyroid and my TSH was 11.8, which I now know is pretty high. My T3 was 8.2 back in January, and T4 was 40 back then, also high. The ER doctor started me off with a prescription of Synthroid, .075 mgs. I hope to get the TSH down to 1, so I could rule the thyroid issue out if I don't feel better at that level. I've read several places where 1.0 is the level people feel better. But I'm still waiting for my ferritin results from my last doctor.
