hi everyone, I'm new to the boards. I was wondering how low should ferritin be to have symptoms? I have battled low ferritin for 5 yrs. In 2007 i had to have iron shots as my ferritin was 7 but my hemaglobin was ok, my ferritin only got up to 58 so i thought i was ok. No doctor told me what it should be. I recently got bloodwork and my ferritin is at 16 and my hemaglobin at 142 so the doctor said it's not that causing your symptoms, but from what i'm reading here i beg to differ. I am extremly tired but can't sleep, cold, restless legs,feel like i'm on a boat at times,weak legs,extremly tight neck/shoulder muscles that is not relieved by massage. The ranges for ferritin on lab results are 6-136 and i'm at 16 so could this cause my symptoms? getting pretty upset with these doctors. please help!
