Good morning Laura!...I do not have any personal experience with this, but know several who have, (several here at work)...and for many it was well worth it...and the pain was instantly gone.
Of course everyones case is different, but it may be well worth a try. However, I do realize that you seem to have multiple issues, and fixing one thing may lead to other problems in other area's.
Hope it is a possible for you!
