How Can I Tell if I Have Sinusitis or Just a Cold?

Distinguishing between sinusitis and a common cold can be tricky since they share several symptoms, but key differences in timing, location, and symptom patterns help differentiate these conditions.

Duration is the biggest clue: A typical cold lasts 7-10 days with symptoms gradually improving. Sinusitis, however, either persists beyond 10 days or initially improves then worsens again. If your symptoms are getting worse after day 5-7 or haven’t improved after 10 days, you likely have sinusitis.

Location of pain differs significantly: Cold symptoms primarily affect the nose and throat with minimal facial pain. Sinusitis causes distinct facial pressure and pain in specific areas:

• Forehead (frontal sinuses) 

• Between and behind the eyes (ethmoid sinuses) 

• Cheeks and upper teeth (maxillary sinuses) 

• Back of the head (sphenoid sinuses) 

Nasal discharge characteristics: Cold discharge typically starts clear and watery, may briefly become thicker, then returns to clear as you recover. Sinusitis often produces thick, yellow or green discharge that persists or worsens over time. 

Symptom patterns: Cold symptoms include runny nose, sneezing, mild cough, sore throat, and low-grade fever. These symptoms peak early then gradually improve. 

Sinusitis symptoms include facial pain/pressure, thick nasal discharge, reduced sense of smell, post-nasal drip, and sometimes tooth pain. These symptoms persist or worsen rather than improving. 

Pain with movement: Sinusitis pain typically worsens when you bend forward, lie down, or move your head suddenly. Cold-related congestion doesn’t usually cause this positional pain. 

Response to decongestants: Cold symptoms often improve with over-the-counter decongestants. Sinusitis may show temporary improvement but symptoms return quickly once medication wears off. 

Fever patterns: Colds rarely cause fever in adults, and when they do, it’s usually low-grade and brief. Sinusitis can cause higher fevers (101°F or above), especially if bacterial infection is present. 

Timing after cold symptoms: Many sinusitis cases develop after initial cold symptoms improve. If you felt better for a few days then symptoms returned or worsened, sinusitis is likely.
