My 7 year old daughter developed a severe case of sore throat. It took 2 rounds of Antibiotics to clear the throat infection. By that time, the left ear was infected. There was some pus in the ear canal and she was prescribed some Antibiotics and eardrops.
A week gone by and the left ear still feels (and sounds) muffled. The infection didn't clear and I told my wife it's time to try UT. She collected fresh urine from my child 3-4 times daily and used a dropper to deliver urine drops into the ear canal and soak for 5-10 minutes. My wife also mixed a teaspoon of urine into fruit juice for my child to drink. This continued for 2 days, 4 times daily.
Today, my child hear normally, with very tiny muffles. It is improving speedily. I'm sure the problem will be gone within 1-2 days.
