If you are in pain I would call your doctor, he/she may want you to go see an ophthalmologist just to get it checked out. Did you have your eyes examined before starting plaquenil? If so, when was that? Lupus can make you feel very fatigued, fatigue like you've never experienced before. That is the one thing I think we all struggle with. You jave to learn to listen to your body and rest when you need to.
Feel free to ask us any other questions you may have, that is what we're here for. Take care
