Amy, very good advice from everyone.
In my case, both of my hips looked equally bad on X-rays, but my right one was hurting much more than the left one. No bone density issues. I had my right one resurfaced last April, and the left one a few weeks ago, in October. In the 6 months between the surgeries, my left hip started hurting really bad, and I got to the point that I could barely walk for the last few weeks before my surgery. At that point, there were many times I wished I had bitten the bullet and had both of them done last April, even though the recovery would have been a little longer.
You are young, but there are many on this site who were younger than you are when they had the surgery. Your hips will not get better by themselves, so there really are no alternatives, other than wait and stay in pain or have surgery. It is a scary decision, but most everyone here who have already made the decision and had the surgery says they wish they had done it long before they actually did. Now, when I can walk with no pain in either hip, it is absolute heaven. The relief is enormous. And I do wish I had not waited as long as I did! And the end result was definitely worth it, even though I had two recoveries to deal with. The recovery time, whether you have one side done at a time, or both at the same time, is only a short period in your life and then you will have no more hip pain!
Whichever way you decide to go, I wish you the very best of luck! You have consulted two excellent surgeons, and I'm sure you will have a great result.
