I also am dealing with LOW FERRITIN and I agree that the symptoms associated with it are awful! At my request, I asked my doctor to check my Ferritin in Dec. 2010 and it came back as 20! She sent me the results and said all my labwork was normal with no evidence of anemia & my iron stores were fine! 20!!! Are you kidding me???
Snobetty, you are very lucky you have a good doctor. I'm curious to know what your Ferritin was at before and now? My doctor's response made me pretty much give up on the "whitecoats" and just start to treat myself. I started taking Garden of Life Raw Iron and Lactoferrin. I got retested in January 2012 and was excited to have raised it to 55! But I know it needs to be much higher than that to regrow hair, get better digestion, stop having freezing cold flashes, poor sleep quality, feelings like my cells have no energy and like I don't get any energy from the food I eat.
One big reason to monitor your Ferritin closely is that zinc is extremely antagonistic to iron. I haven't been taking my iron regularly lately and now I can tell that I've got that low cell energy feeling back again! I'm planning to get my level retested soon....but I was taking more zinc lately and I think I pushed my iron lower again!!! :(
Anyway, here are some of my favorite links to articles about iron, both low and high are mentioned in these articles:
