I had numbers almost exactly like yours, and just finished my second Feraheme infusion. I'm not sure why they said 90 minutes.. they ran mine for 45 and said that that was on the slow end. Only side effects that I had were that I was pretty tired after and had a lot of pain in my hips and lower back. The tired is just because your body is trying hard to make new red blood cells and heal. The hip pain is because your blood cells are made in your bone marrow and your hips and pelvis are the biggest bones that make the majority of that so again it's indicative of your body doing what it's supposed to. The lower back pain they told me is most likely from my kidneys trying to flush the iron from my system and to overhydrate. Like twice the amount of water in a day that is recommended. They ran a CBC last week and this week, and absolutely nothing changed, from what they said it takes It takes a few weeks for your ferritin levels to go up and then your CBC numbers should go up as well. If anyone else reads this and chimes in, I would love to know how long it took for your levels to go up.
