Hi, I Am A Renal Transplant Patient (10 Years Post-transplant).

Hi,
I am a renal transplant patient (10 years post-transplant). I have always had issues with low iron and in May 2018 I was given an iron infusion. Since them my iron levels are good but my ferritine keeps rising..it is currently 1038 and my blood count is 8.8.
My Drs seem to be confused by the matter and discussing the results between many specialist (I'm under specialist care for a number of diseases).
Are you able to give any insight as I feel in the dark, please?
Thanks
