What to tell us about your symptoms

Sinus inflammation can cause facial pressure, nasal congestion and drainage. A cold or allergies can produce overlapping symptoms; the color of mucus alone does not settle the cause.

What the video visit can help with

The timeline matters. Tell the clinician whether symptoms have been steadily improving, lingering or getting worse after you started to feel better. Explain what you have used for relief and any medicine allergies.

When an examination or testing may be needed

Some concerns can be evaluated through a detailed history. Others need an in-person examination, especially when symptoms are severe, unusual or persistent. The video visit should clarify that choice, not promise to replace every examination.

Discussing treatment

Many sinus infections improve without antibiotics. Your clinician can discuss symptom relief and whether the overall pattern suggests a treatment that needs a prescription. Any prescription goes to the pharmacy you select.

When to get care in person

Seek prompt in-person care for a severe headache, concerning facial or eye swelling, vision changes, or symptoms that make you feel seriously ill. Trouble breathing or confusion calls for emergency care.

Before your visit

Have the symptom start date and the names of nasal sprays, allergy medicines or pain relievers you have used. Mention a recent illness and whether it seemed to improve before symptoms returned.

Questions about this care

Do sinus infections always need antibiotics?

No. Many do not. The clinician considers your history and symptom pattern rather than prescribing an antibiotic solely because you have congestion.
