I have noticed for a few years that one of the small glands on my areola has been clogged, I have had two kids and previously been unable to nurse them due to low production, we just ha our third baby and I am able to nurse just fine but I have noticed that the glam is more swollen, contains a hard puss like substance and is sore, do I need to have it looked at or is it somehing that will just correct it's self?
