I had the surgery on March 16th. You already know it is going to hurt. You already know to look for alternatives. You and you doctor must have already discussed this at length and have decided it is right for you, right? If not, then I encourage you to really dig into this forum and learn as much as you can. I also encourage you to look at as many other resources you can (online, 2nd opinion, etc) before making your decision.
I am 46 years old, in moderately good health (a little overweight, but not obese), severe obstructive sleep apnea (AHI=47), and found to be CPAP intolerant. I elected to have the surgery based on the size of my tonscils and uvula. I have yet to get the final costs, however this is what my un-negotiated explanation of benefits say:
Hostpialization: Includes 24 hours in the ICU, and use of facilities - $8900.00
Anastesia: Includes them knocking me out, and waking me up! - $1100.00
Dr Fees: Have not seen this one yet, but so far 2 office visits - $ 300.00
Now, remember, these costs get negotiated down, then my I pay my deductable, then 10% of the balance. I am figuring this will cost me around $1200 or so (which will be taken from my flexable spending account)
I started a thread a day or so ago about revocering from surgery. Some of the things I found worked and did not during my recovery. Again, I would encourage you to look over all this stuff so you know what you are in for. Since you are younger than I am, I would suspect you to tolerate the surgery better than if you were older. It does hurt, but has not killed me...
Best of luck to you!
