How do you know your sinus infection is gone?

You can determine that your sinus infection has resolved when symptoms such as facial pain, nasal congestion, and pressure have significantly diminished or disappeared. Additionally, a reduction in post-nasal drip, improved sense of smell, and relief from headaches typically indicate recovery. If you notice these improvements over several days, it's likely that the infection has cleared. However, if symptoms persist or worsen, consulting a healthcare professional is advisable.
