Sinus Infection Treatment in Southlake, TX

Most sinus infections are viral and resolve without antibiotics. That is not a brush-off, it is the actual medicine, and the useful part of the visit is treating what genuinely helps while making sure you are not in the minority who need more.

When it is probably bacterial

Three patterns raise the odds enough to justify antibiotics.

• Symptoms lasting more than ten days with no improvement at all
• Severe symptoms from the start, with fever above 102 and facial pain, for three or more consecutive days
• Symptoms that were improving and then clearly worsened around day five to seven, the so-called double worsening

Outside those patterns, an antibiotic is unlikely to change anything except your gut flora.

What does not tell us

Mucus colour tells us nothing about whether bacteria are involved. Green and yellow mucus appear routinely in ordinary viral colds because of the immune cells in it.

Facial pressure alone, without the patterns above, is not enough either. Neither is the fact that antibiotics helped last time, since most people improve on day ten regardless of what they took on day eight.

What actually helps

• Saline irrigation. The most effective single intervention and the most underused. A neti pot or squeeze bottle with distilled or previously boiled water, twice a day. It genuinely works, and it works for viral and bacterial sinusitis alike.
• Intranasal corticosteroid sprays. Meaningful benefit, particularly with an allergic component. Aim the spray outward toward your ear, not up the middle, which is where most people spray and why they get nosebleeds.
• Analgesics for pain and fever.
• Steam and warm compresses, for comfort.

Oral decongestants provide short-term relief and raise blood pressure, so we are careful in patients with hypertension. Decongestant nasal sprays work well for three days and then cause rebound congestion, which traps people for months.

When we do prescribe

Amoxicillin-clavulanate is usually first-line, for five to seven days in most adults. We choose differently with a penicillin allergy, recent antibiotic exposure or treatment failure.

If you are not improving after three to five days on an antibiotic, come back rather than waiting out the course. That usually means either the wrong bug or the wrong diagnosis.

Recurrent and chronic sinusitis

Four or more episodes a year, or symptoms lasting beyond twelve weeks, is a different problem and repeating antibiotics is the wrong answer.

We look for allergic rhinitis, nasal polyps, structural problems like a deviated septum, dental infection in the upper molars, and rarely immune deficiency. CT imaging and an ENT referral make sense at that point.

Untreated nasal and sinus disease also makes asthma harder to control, and treating the nose reliably improves the chest.

Red flags

Vision changes, double vision, swelling or redness around the eye, severe headache with neck stiffness, confusion, or swelling of the forehead.

These suggest the infection has spread beyond the sinus and need emergency evaluation the same day, not an appointment next week.
