question: MY DAUGHTER IS 21, SHE IS A SINGER WORKING HER VOICE 4 TO 6 HOURS PER DAY. SHE HAS BEEN FIGHTING A STRAINED AND SORE THROAT FOR MONTHS. SHE SAYS SHE HAS YELLOW BUMPS AT THE BACK OF THE THROAT, FEELS SORE AFTER SINGING, LIKE SOMETHING IS STUCK IN HER THROAT. NO FEVER, NOT SORE WHEN NOT SINGING. GARGLES WITH WARM SALT WATER, USING A HUMIDIFIER, NOTHING IS HELPING.
