A blocked, painful sinus can quickly take the shine off a holiday. Long flights, constant air conditioning in hotels and villas, dust, and tropical allergens all make sinus infections common among tourists in Koh Samui. If you have facial pressure, a stuffy nose, and that heavy-headed feeling, our English-speaking doctors can examine you the same day and get you comfortable again — walk in to our clinic in Chaweng or Lamai, or ask about a hotel visit.

What is a Sinus Infection?
A sinus infection, or sinusitis, is inflammation of the air-filled spaces behind your nose, cheeks, and forehead. When these spaces become swollen and blocked, mucus builds up and causes pressure and pain. Sinusitis is described as acute when it lasts up to a few weeks (the usual holiday scenario) and chronic when symptoms drag on for many weeks or keep coming back. Most cases start as viral, following a cold, and clear up on their own; a smaller number become bacterial and may benefit from antibiotics. Telling these apart is the key to the right treatment.
Symptoms to Watch For
– Facial pain or pressure around the cheeks, eyes, or forehead
– Blocked or stuffy nose
– Thick nasal discharge or post-nasal drip
– Reduced sense of smell or taste
– Headache that worsens when bending forward
– Mild fever, tiredness, or a cough
Sinus problems often come alongside a sore throat — see our sore throat treatment in Koh Samui page if that is troubling you too.
Causes & Risk Factors
In travellers, sinusitis is often triggered by:
- A recent cold or upper respiratory infection
- Air-conditioning and dry cabin air on long flights
- Dust, pollen, and tropical allergens
- Pressure changes from flying or diving
- Nasal allergies or a deviated septum
If your symptoms feel more like a chest or throat cold, our upper respiratory tract infection in Koh Samui page may be a better fit.
How We Diagnose It
Our doctor asks about your symptoms and how long they have lasted, then examines your nose, throat, and ears. The duration and pattern of symptoms usually tell us whether the cause is likely viral or bacterial. If symptoms are severe, persistent, or unusual, we can arrange further assessment or imaging. In most cases we can diagnose and treat you in a single walk-in visit.
How We Treat It
Because most sinus infections are viral, treatment often focuses on relieving symptoms and helping the sinuses drain — saline nasal rinses, decongestants, nasal sprays, antihistamines where allergy plays a part, and good hydration. When the picture points to a bacterial infection, or symptoms are severe or lasting more than about ten days, our doctor may prescribe antibiotics. We discuss treatment in general terms here; your doctor will tailor the plan to you. For current pricing, simply message us on WhatsApp.
Recovery & Aftercare
Most acute sinus infections improve within one to two weeks. To recover faster, stay well hydrated, rest, use saline rinses, and try steam inhalation to loosen congestion. Reducing time in heavily air-conditioned rooms can also help. If symptoms have not started to improve within around ten days, get worse after initially improving, or keep returning, please come back so we can reassess and consider whether antibiotics or further checks are needed. We are happy to follow up over WhatsApp during your trip.
When to Seek Urgent Care
Seek care promptly if you develop:
- Swelling, redness, or pain around the eyes, or changes in vision
- A severe headache, stiff neck, or confusion
- A high fever that will not settle

FAQ for Tourists
Q: Do I need antibiotics for a sinus infection?
A: Often not. Most sinus infections are viral and improve with symptom relief and time. Antibiotics are reserved for cases that appear bacterial, are severe, or last more than about ten days.
Q: Can I fly with a sinus infection?
A: Usually yes if you are otherwise well, but blocked sinuses can make pressure changes uncomfortable. Decongestants before the flight may help — ask our doctor for advice.
Q: Is a sinus infection contagious?
A: The sinus infection itself is not usually contagious, but if it started from a viral cold, that cold can spread to others.
Q: What is the difference between acute and chronic sinusitis?
A: Acute sinusitis lasts up to a few weeks and is the usual holiday type. Chronic sinusitis lasts many weeks or keeps returning and may need further assessment.
Q: How can I relieve sinus pressure quickly?
A: Saline nasal rinses, steam inhalation, staying hydrated, and decongestants can ease pressure. Our doctor can recommend what is best for you.
Q: Do I need an appointment?
A: No — we are a walk-in clinic. You can also message us on WhatsApp to ask a question or arrange a hotel visit.
