Well, sinusitis is an infection of the sinuses and any infection can make you feel like you have no energy (lazy), so I would say yes, it definitely could, especially if you're running a fever with it.
Get plenty of rest, drink plenty of fluids (will help keep the sinus congestion thinner andeasier to blow out) and use whatever meds your doc has prescribed.
I am pretty sure it can. II 've had it a couple of times and it hits me just like a bad cold. I feel like I can sleep for a week when I have sinus issues. I am guessing it has to do with the fact that since you can't breathe normally it messes with your sleep habits.
Not lazy but definitely drained out of powers
