Shannon, usually fusion can't be seen on x-ray until at least 3 months. It's unlikely you'll be completely fused at that point, but hopefully you'll be well on the way.
You'll still need to be careful for quite a while, but you'll have some restrictions lifted and will feel a lot better.
Kellie, I'm sorry you're still in so much pain. It sounds like your doctors are at least trying to keep you medicated. That's a blessing! There have been people here whose doctors wouldn't prescribe past 6 weeks! Ouch!!!
Killian, how fantastic is that, that you're already off your pain meds and can walk so far! You must be thrilled! Keep up the good recovery work and don't fall into the trap of overdoing it because you're feeling so much better.
And doesn't that just go to show how we're all so different! This board is so good for information, but we all need to remember to use it as a guideline, not as a measurement of success or failure. Each situation is unique and each person recovers differently, even though we all have some similarities.
