With medicine included, I've spent under $800 out of my own pocket with NO wait time. Surgery probably wouldn't cost
more than another $500 - $1000 I'm guessing. If you knew exactly what the problem is, you could bring your MRI and CT scans, could see 1 ENT and 1 neurologist and then push to have it removed, saving you a ton of money. You would pay only around $100 total to see them BOTH! Your biggest expense will be the plane ticket here, about $1200 from the USA if you shop around.
