Sounds like you've made a good decision for you.
And it sounds like you've put alot of effort into every intervention possible, within your contro,l to remedy the problem and it just hasn't worked.
Sometimes it doesn't.
I think your attitude and openess is exceptional regarding this, especially for a young male, and I applaud you!
It is important to research what procedure you will have done and where you will have it done and get written statements of all inclusive costs as well as anything that will be extra.
Getting this kind of info is typical and expectable in medical tourism.
Very *strongly* consider having your surgery done in a JCI (Joint Commission International) accredited hospital.
There is a list of JCI accredited facilities in the link I will provide below.
You can also get an idea of costs for your procedure.
Facilities or entities that work with a given facility often offer packages. Explore these.
And carefully arrange for what you will do after your release from the facility post surgery.
If you do not stay in the facility for a couple of days or so after the procedure, then you will want to think about planning to stay nearby (packages often offer this option) to be sure that there are no post-op issues for which you will need to be close to the facility to be checked.
It's a buyer's market in your situation. Do not hesitate to ask for lots of info and get it!
You will also need to request that your physician write a special dietary order for you up front as what you will be served to eat will be determined strictly by his/her order.
Eat well and research well and forge ahead!
