I had similar problems for 3 months. I went to a ENT and he said I had LPRD and that the acid was coming up in to my throat which is causing sore throat, hoarsfleness etc. I got rid of it by following these very strictly
1. Check which medicine is working - Nexium, Aciphex etc. You need take them for a month and see if they r working. Also try to increase the dose.
2. Be careful on what you eat and when you eat. You can get lot of info on the net about what to and what not to eat.
3. Sleep on a slanted bed, raise ur bed by 6 inches.
4. NO SMOKING.
5. NO COFFEE.
6. NO CHOCOLATE.
7. Relax and do some stress relieve excercise.
Dont try but just make sure you follow every one the above and you will do ok.
