Your iron levels are very mildly low and the hemoglobin is absolutely normal.
The main thing that we look at with iron levels is the hemoglobin level.
If the hemoglobin level is normal as you have stated then these iron levels are usually not something to worry about at all.
Hemoglobin levels can normalize even before the total iron stores indicated by the ferritin is back to normal, so yes that can happen.

MIldy low, yes but at the bottom end of the acceptable range. I also experience symptoms of iron deficiency at this range: fatigue, back ache and muscle aches, difficulty concentrating, pale skin, dark rings under eyes. I usually have parenteral iron repletion therapy as up till now I have been unable to tolerate oral iron. Although now I am able to tolerate Sodium Feredetate (Sytron) I have avoided an iron infusion this time - Usually 500mg Ferrinject about every 3 months. The underlying cause (IBD) is being treated now. My HB is the best its been in years (never above 12) but Iron stores are low.


I am experiencing back pain lately, since taking the Sytron and I wonder if this is a side effect of iron repletion or a symptom of deficiency?

Expert:  Dr. SH replied 3 years ago.
Back pain is neither a symptom of iron repletion or deficiency.
It may be a muscular backache related to overexerting your back probably or may be related to disc disease or bone disease of your back.
Its most likely not related to your iron at all.

Hi Dan,
How is your back pain now?
Please let me now.
Customer: replied 3 years ago.
Well it appears my symptoms were caused by iron overload. I stop taking it for a couple of days and all aches and pains went away. I have titrated to 5ml per day with no problems. I am taking Sytron btw.
