In brief: See your doctor

If it has lasted that long, you should see your doctor to make sure it is not a small skin cancer.
Probably has nothing to do with your iron.

In brief: Herpes

Most likely it is a cold sore (herpes simplex virus 1).
It can go latent for a very long time and will show up only when your immune system weakens. Weakening of the immune system can be due to stress. Most likely this is not caused by low iron levels. Please consult your doctor for more information.
