That's likely what it was. What mob were you fighting? Certain NMs like Briareus, Cottus, Kukulkan, and others have a special version of Curse that, while its active, prevents you from recovering HP and MP by any means and can only be removed by Sacrifice.
If I may ask, what belt are you using on your Paladin? If you are using the Accursed Belt, it has a hidden effect of that same special Curse, which makes it impossible for you to recover HP and MP with it equipped.
Bah, beaten to the punch.
