chacer,
I'm sure you are really tired of surgery and dread the thought of having any more. But, in the future, you may decide that if a surgery can make it so that you are not in so much pain and can function better, it might be worth it.
From you initial description, it sounds like you had pilon fractures of the distal tibias. These, unfortunately, result in a high rate of traumatic arthritis in the ankle joint.
It used to be that about the only thing that could be done in young patients with significant ankle degenerative changes was an arthrodesis of the tibiotalar joint (ankle fusion). But, with the advancements in total ankle joints, you may, in the future, be a candidate for a total ankle.
And, again, I know you are tired of surgery, but there are also some smaller procedures that can be done, such as ankle arthroscopy to do some "house cleaning". Remove scar tissue, osteophytes, etc, making the ankle less painful.
Sure, there is nothing that is going to make your legs "normal", but it might be better. These are just some things to keep in the back of your mind, for later. They are just some options. You sounded like you were sort of at the end of your rope.
There are also some pain management techniques that could provide you with some pain control. A spinal stimulator may provide you with relief from the extremities.
It sounds like you know about most of the other methods and have tried them at one time or another. But, you do have to remember that no one is really pain free, it is just trying to get the pain to a level at which you can function.
I know it is hard to change physicians, but if you are not getting the results you desire from your current pain management clinic, you may have to change. And, you may have to travel a ways. Unfortunately, there are no real easy answers, but does not mean that you should just give up. There are options out there, but you do have to be proactive for yourself.
Good luck. Hope you find a pain management method(s) that work for you.
