I'm 28, my ferritin level was checked, test result was 10.8 and the dr has not shown concern. should i get 2nd opinion, how should this be treated?

Don't treat a lab: This is just below the lower limit of normal for a young woman for most labs. It would be worth looking at your monthly losses and dietary intake -- if the iron loss is heavy and you don't eat a lot of meat and don't take a supplement with iron, this is probably your explanation. If this isn't the case, I'd check to be sure you're not losing blood from your gut (bleeding ulcer, tumor).
