So my hemoglobin levels and all that "fun stuff" have been really low (like under half of what they're supposed to be) and dropped more since they last checked it 2 months ago so I've Been going for IV iron infusions everyday for the past week and have 3 left (they've got me doing 10 treatments) and my lower back kills after some of my treatments but not others, any other moms experience this as a result of iron treatments? I literally have no other real side effects besides this back pain, They're giving me this brand called Venofor, idk if the brand would even make a difference; I'm sure it's just my body adjusting to all the extra iron it needs but it's just really annoying and no matter what I do (stretch, lie down, etc.) nothing seems to help it, the paperwork says that it may be a side effect but I still might call my hematologist or OB's office and talk to somebody about it.
