I tried sound therapy about 7 years ago at a "health fair". My sinuses were really bothering me that day, so we tried it for my sinuses. OMG!!!! It was great! Totally relaxing and it did clear my sinuses and it lasted about a week, and that was just a short "try it" session. I would definitely try sound therapy again! As a bonus, it also lifted my down mood on the gray, cold, winter day.
