I have had 3 Iron infusions sense this past wednesday and they dont hurt at all they take anywhere from 2 to 4 hours . I have had a blood transfusion and that made me feel funny. I only got sleepy after the Iron and a slight headache.No worries. I had a gallbladder surgery the doc cut the wrong thing and then I became anemic not sure why but here I am with a hemogloban of 4.1
good luck you'll feel a lot better
