What could be causing a mild sore throat that has come and gone for five to six months, and how should I treat it, since treatments like salt water gargles, Betadine, and prescriptions from an ear, nose, and throat doctor (antibiotics, antiallergics, and antacids) only offer temporary relief?
Since antibiotics and antacids only provide temporary relief, the cause might be chronic irritation rather than an active infection. Common culprits include laryngopharyngeal reflux (silent reflux), where stomach acid irritates the throat, or ongoing post-nasal drip from allergies. I recommend discussing a trial of daily generic proton pump inhibitors (like omeprazole) or generic nasal steroid sprays (like fluticasone) with your doctor. Staying well-hydrated and using a cool-mist humidifier at night can also soothe the tissue. Please follow up with your ear, nose, and throat specialist for a detailed examination to pinpoint the exact cause.
