If you talk to the guy that sold you the Discus and his are not showing any signs of this, I definitely think it may be just stress as emile suggests. From his avatar it looks like he may be a discuss keeper, so it is reassuring to hear his input on this. Just be vigilent in watching for improvement with his suggested treatment, and if they seem to worsen this may be more than just stress.
Another experienced discus keeper is our moderator, Pinkertd. You might pm her for another opinion on this. I'm wishing the best for you and your little fishies.
I hope that all this is is stress and your little guys are feeling better soon.
