Woman struggling with sinusitis

Sinusitis can leave you feeling blocked up, achy and generally run down, and one of the first things most people want to know is simply how long it is going to last. The answer depends largely on whether your sinusitis is viral or bacterial, and knowing the difference can help you decide when it is time to seek treatment rather than wait it out.

At Nettles Pharmacy in Tooting, our GPhC-registered team can assess your symptoms and, where appropriate, provide treatment through the NHS Pharmacy First service. If your symptoms are not settling, contact us or speak with our pharmacy team.

Quick Answer: Viral sinusitis usually clears within 7 to 10 days as part of a cold. Bacterial sinusitis can last longer, sometimes up to two to three weeks, and may need treatment if symptoms are severe or do not improve. Pharmacy First in Tooting can assess and treat suitable cases without needing a GP appointment.

Viral Sinusitis: What to Expect

Most cases of sinusitis start as a viral infection, often following a cold or flu. Viral sinusitis tends to peak within the first few days and then gradually improve.

Typical features of viral sinusitis include:

  • Symptoms lasting around 7 to 10 days
  • Gradual improvement rather than sudden worsening
  • Clear or slightly cloudy nasal discharge
  • Mild facial pressure rather than severe pain

Bacterial Sinusitis: How It Differs

Bacterial sinusitis is less common but tends to last longer and can feel more severe. Symptoms lasting longer than 10 days, or that worsen after initially improving, may suggest a bacterial cause.

Signs that may point towards bacterial sinusitis include:

  • Symptoms persisting beyond 10 days without improvement
  • A high temperature or feeling generally unwell
  • Thick, discoloured nasal discharge
  • Severe pain around the face, eyes or teeth
