It worked for me when I had a longstanding ear infection and pain when listening to headphones -- after nine months I gave up on two doctors and their medications, one of them a specialist mind you, and took an alternative route.
Obviously, if you try something and you don't notice improvement or things get worse you should seriously consider stopping and doing something else. It never ceases to amaze me the different opinions one can get if they see three doctors.
I had a more serious problem a few years ago and consulted three ENTs, the second one was a world-renowned specialist and the third was the head of the ENT department at Cedars-Sinai Medical Center and each had drastically different opinions. The first two said surgery was necessary, but each had notably different ideas as to the best procedure and the last said do nothing unless it becomes unbearable. I still haven't gone under the knife and it has gotten better.
Consulting with a doctor is always good advice, but not always the be all and end all.
