| Re: What could this be?
Enlarged spleen and naps brings to mind mono (infectious mononucleosis), although it could be many other things. Nosebleeds suggests high blood pressure. Fatigue can also have something to do with the heart. Are you sure it's his spleen or is it his abdomen that is enlarging? My husband was very tired and started retaining a lot of fluid, especially in his abdomen - turned out he was in congestive heart failure, but he was felling lousy for quite a while before that. The retaining fluid happened relatively quickly, over a period of a week or so. (He's much better now.)
I'd take him to the doctor, just in case.
Good luck.
