I think the prednisone/no strenuous activity thing may depend on dosage and diagnosis. Last time I was on prednisone, the doctor said the silver lining would be that I'd feel more energetic and that it might be a good time to get some extra miles in on my bike training. Of course, since you're also battling an at least borderline infection and one that would seriously cut into your energy at that (sinus infection or inflammation) I would imagine you're in a different situation. In my case, the prednisone left me temporarilly energized and free of stomach pains. So my vote goes with all the folks saying "listen to your body and give it what it needs and demands". Hope you're back in shape quick, by whatever route. I've heard that staying in shape helps keep allergies under control, but since allergies and the medications against them can keep you from staying in shape it's quite a balancing act: working out when you can, resting up when you need to. Sounds like you're aware of that and managing pretty well. Keep up the good work.
