Health officials have described this year’s flu season as one of the most severe in the past 25 years. Across Texas, healthcare providers have seen higher case numbers, stronger symptoms, and longer recovery periods compared to recent seasons.
While that information can feel unsettling, it is important to remember that most people recover fully with supportive care. The key is understanding your symptoms and recognizing when they may require medical evaluation.
Respiratory illnesses often share overlapping signs. Congestion, cough, fatigue, and facial pressure are common complaints this time of year. Because symptoms can look similar, many patients are unsure whether they are experiencing a sinus infection, the flu, or another condition entirely.
Knowing the differences can help you make confident decisions about your care.
What Is a Sinus Infection?
A sinus infection, also called sinusitis, occurs when the sinus cavities become inflamed or infected. This often develops after a cold or upper respiratory infection.
Sinus infections tend to cause symptoms that are localized in the head and face. These may include:
- Facial pressure or pain
- Nasal congestion
- Thick yellow or green nasal discharge
- Headache
- Reduced sense of smell
- Ear pressure
- Symptoms lasting longer than 10 days
Pain that worsens when bending forward or pressure around the eyes and cheeks is especially common.
Most sinus infections are viral and improve without antibiotics. However, bacterial sinus infections may develop if symptoms persist or worsen.
What Is the Flu?
The flu is a viral respiratory illness that affects the entire body. Unlike sinus infections, the flu typically begins suddenly and often causes more intense systemic symptoms.
Common flu symptoms include:
- High fever
- Chills
- Body aches
- Significant fatigue
- Cough
- Sore throat
- Headache
During a particularly active flu season, patients may experience stronger body aches and prolonged exhaustion. Many people report feeling drained for days or even weeks after the initial illness.
Unlike sinus infections, the flu usually causes full-body discomfort rather than isolated facial pain.
Why The 2025-2026 Flu Season Feels Different
This year’s flu season has resulted in increased hospital visits and more widespread illness across communities. Factors such as viral strain changes and lower immunity levels may contribute to the higher number of cases.
However, severity does not mean inevitability. Most individuals, including children and healthy adults, recover without complications.
The important step is recognizing when symptoms are typical and when they may signal something more serious.
When Should You Seek Medical Care?
While many sinus infections and flu cases can be managed at home with rest and hydration, medical evaluation is important if you experience:
- Difficulty breathing
- Persistent or very high fever
- Chest pain or pressure
- Severe facial swelling or pain
- Confusion or dizziness
- Signs of dehydration
- Symptoms that improve and then suddenly worsen
Worsening symptoms after initial improvement may indicate a secondary infection or complication.
If something feels different or more intense than previous illnesses, it is always reasonable to seek evaluation.
Getting Clarity About Your Symptom
It is not always easy to distinguish between a sinus infection and the flu without an examination. Diagnostic testing and a clinical evaluation can provide answers and guide appropriate treatment.
Seeking care does not mean assuming the worst. In many cases, evaluation simply provides reassurance and a clear plan for recovery.
