Sore throat from acid reflux ,try gargling with salt and water in the morning for 1 minute . I take 20mg of Miracid(omeprazole) one in the morning and one before dinner (5pm). I was diagnosed with Laryngopharyngeal reflux,silent reflux. No acid or heartburn but constant mucus and hacking all day long! I noticed it was tolerable when I lost weight, stopped coffee, beer,sweets ,many fruits and dairy products. Vegetable's and baked chicken are my friends.
