Sinusitis: When is it Sinusitis or Allergies?
By Doctors On Demand, South Africa
What Is Sinusitis?
Sinusitis, commonly known as a sinus infection, occurs when the tissue lining the sinuses becomes inflamed and infected.
The sinuses are air-filled cavities located behind the forehead, cheeks, and nose. When these spaces become blocked and filled with fluid, bacteria can grow, leading to infection and discomfort.
Sinusitis is a common condition that can affect people of all ages. It is often confused with rhinitis or ‘hay fever’. It is therefore important to have a medical evaluation to determine the exact condition and correct treatment.
What Is Rhinitis?
Rhinitis is when the inside of your nose becomes irritated or inflamed. It can cause one or more of these symptoms:
- A blocked or stuffy nose
- A runny nose (from the front or down the back of the throat)
- Sneezing
- An itchy nose
Rhinitis is often confused with sinus infections because they can have similar symptoms. However, they are not always the same condition. Allergic rhinitis is a very common condition in South Africa related to allergic triggers. Keeping up to date with your local pollen count throughout the year and controlling allergic triggers in your home environment may assist with reducing symptoms.

Risk Factors for Sinusitis
Certain individuals may be more prone to developing sinusitis, including those with:
- Allergies
- Asthma
- Frequent respiratory infections
- Smoking habits
- Structural nasal abnormalities: nasal polyps, deviated septum
- Immune system disorders
Identifying and managing risk factors can help reduce the likelihood of recurrent infections.
How Is Sinusitis Diagnosed?
Healthcare providers typically diagnose sinusitis based on symptoms and medical history. During an online consultation, your doctor may assess:
- Duration of symptoms
- Severity of facial pain and congestion
- Presence of fever
- History of allergies or previous sinus infections
In some cases, further testing or referral to an ear, nose, and throat (ENT) specialist may be recommended.
Treatment Options for Sinusitis
Treatment depends on the cause and severity of the condition.
Home Care Measures
Many cases of acute sinusitis improve with self-care, including:
- Drinking plenty of fluids
- Using saline nasal sprays or rinses
- Inhaling steam
- Getting adequate rest
- Using a humidifier
- Applying warm compresses to the face
- Immune support: sunshine, Vitamin C and zinc-containing foods or supplements
- Allergic triggers: pollen, dust, dust mites, cockroaches, mould and pets
Medications
Your healthcare provider may recommend:
- Antihistamines
- Nasal corticosteroid or decongestant sprays
- Oral decongestants
- Pain relievers for headaches and facial discomfort
- Antibiotics when a bacterial infection is suspected
Antibiotics are not effective against viral sinus infections and should only be used when medically indicated.

At any point of illness when you are feeling unwell or are not sure what to do or which medications you should take, it is safer to see a doctor. An online consultation provides a quick and easy way to assist you with making decisions about your health.
Seek medical advice if you have:
