What is a Sinus Infection?
Your sinuses are air-filled spaces behind your forehead, cheeks, and eyes. When they get inflamed and blocked — usually after a cold — bacteria can multiply in the trapped mucus. That pressure and pain you're feeling? That's your sinuses fighting back.
Viral vs. Bacterial
Most sinus infections start viral and get better on their own in 7-10 days. They only become bacterial — and need antibiotics — if they linger 10+ days or get worse after initially improving.
The Timeline
First few days after a cold, swelling blocks drainage. By day 3-4, you notice pressure and congestion. Most clear up naturally, but some progress to bacterial infection.
When Antibiotics Matter
Not every sinus infection needs antibiotics. Unnecessary antibiotics won't help and increase resistance risk. We recommend them when symptoms point to bacterial infection or don't improve.
Symptoms — What to Expect
Most people with sinus infection notice a combination of these symptoms. They usually peak around day 3-5 and gradually improve.
Facial Pain & Pressure
Worse when bending forward or lying down. Usually concentrated around the cheeks, forehead, or between the eyes.
Thick Nasal Discharge
Yellow or greenish mucus. Thicker and more persistent than typical runny nose. Post-nasal drip is common, especially at night.
Nasal Congestion
Stuffy nose that doesn't improve much with decongestants alone. Both nostrils usually affected.
Loss of Smell/Taste
Your sense of smell decreases because congestion blocks the olfactory nerve. Usually returns when swelling goes down.
Headache
Usually frontal (forehead area) and tied to sinus pressure. Ibuprofen or acetaminophen helps while waiting for swelling to decrease.
Cough (Especially at Night)
From post-nasal drip irritating your throat. Worst when lying flat. Propping yourself up with extra pillows helps.
Green Mucus Doesn't Automatically Mean Antibiotics
The color of your mucus (yellow or green) doesn't tell us if it's viral or bacterial. Both infections produce colored discharge. We look at duration and progression instead. Symptoms improving on their own? Usually viral. Symptoms getting worse after initial improvement? That's when antibiotics matter.
Your Medications
If we've determined you likely have a bacterial sinus infection and prescribed antibiotics, here's what you're taking and why.
Amoxicillin
Amoxicillin is usually our first choice because it works well against the bacteria that typically cause sinus infections and has a good safety profile. Take the full course even if you feel better after a few days.

If you've had recent antibiotics or your infection isn't responding, we may use Augmentin instead. The clavulanate ingredient helps overcome antibiotic resistance. May cause nausea — take with food.

For patients with penicillin allergies, doxycycline is an excellent alternative. Take it with food and a full glass of water. Avoid dairy products within 2 hours of your dose.

If your symptoms just started in the last few days, we may recommend watchful waiting with supportive care first. Antibiotics work best when we know it's bacterial — and that usually means symptoms lasting 10+ days or getting worse after initial improvement. Your immune system is remarkably good at fighting viral infections.
Red Flags — When to Seek Emergency Care
Sinus infections are usually manageable at home, but certain symptoms signal serious complications that need immediate attention.
Seek Emergency Care If You Have:
- Severe headache that won't go away — Unlike typical sinus pressure, this is constant and doesn't respond to pain medication
- High fever (102°F+) lasting more than 3 days — Suggests infection is spreading beyond your sinuses
- Swelling around your eyes — Especially if one eye is more swollen than the other, or you notice it worsening
- Vision changes or double vision — May indicate infection around the optic nerve
- Stiff neck — Can signal meningitis (rare but serious)
- Symptoms rapidly worsening — After seeming to improve, sudden deterioration is concerning
Orbital Cellulitis (Rare but Serious)
Infection can spread around the eye socket, causing swelling, vision problems, and fever. This is a true emergency. If you notice one-sided eye swelling with fever, go to the ER immediately. This complication is rare but requires IV antibiotics and sometimes hospitalization.
Home Care — What Actually Works
These strategies help your body drain congestion and manage symptoms while your immune system does the healing work. Many people find these more effective than they'd expect.
Saline Nasal Rinse
Neti Pot or NeilMed Sinus Rinse bottle. Game changer for most people. Rinse each side gently 1-2 times daily. Helps flush out mucus and reduce inflammation directly.
Steam Inhalation
Hot shower or bowl of hot water (not boiling). Breathe in the steam for 10-15 minutes. Loosens mucus and helps drainage. Do this 2-3 times daily.
Stay Hydrated
Drink water, warm tea, or warm lemon water. Hydration thins mucus and helps your body fight infection. Aim for at least 8 glasses daily.
Warm Compress on Face
Apply a warm (not hot) compress to your cheeks, forehead, or nose. Feels good and helps relieve pressure. 10-15 minutes at a time works well.
Sleep Elevated
Use an extra pillow or sleep in a recliner position. Elevation helps drainage and reduces pressure build-up at night. This alone helps many people sleep better.
OTC Decongestants
Pseudoephedrine (Sudafed) works well but use only for 3 days maximum — longer use causes rebound congestion. Nasal spray decongestants also work but same 3-day limit applies.
Mucinex (Guaifenesin) Helps Thin Mucus
Guaifenesin is an expectorant that thins mucus, making it easier to drain. Take as directed with plenty of water. Some people find it more helpful than decongestants because it addresses the root problem — thick mucus that can't drain.
Frequently Asked Questions
Your Follow-Up Plan
Most people improve with home care or antibiotics alone. Here's what to watch for and when to reach out:
- After 2-3 days on antibiotics: You should notice improvement. If symptoms are getting worse or not changing, text us back — may need a different antibiotic
- After 7 days: Most people are significantly better. If still struggling, we can discuss next steps
- Recurrent infections (3+ per year): May benefit from referral to an ENT specialist for evaluation of structural issues or persistent inflammation
- Any red flag symptoms: Go to the ER or urgent care — don't wait to text us
