Why am i having night sweats with bacterial sinusitis? this has been for 3 nights in a row.

Night sweats: Night sweats mean you had a fever and it's now coming down. It's the way your body throws off heat. A bad sinus infection can make you run a fever, although most sinusitis does not come with fever. If you are on an antibiotic, this could also be a side effect of the medication. Hard to be sure. See your doctor if you haven't seen one. One-sided sinusitis often means dental issues, so be careful.
