How is your back doing now? I had a failed discectomy at the same level you had fused and now both my legs are just on fire with nerve pain. A fusion might be in my future but the long term outcome kinda scares me, especially only being 26. Also getting out of work for 3 months of recovery is gonna be hard to come by.
Long Post
I don't really have much nerve pain since I had both of my fusions done. Unfortunately I do have pain still most of the time unless I am sitting on a very padded couch or chair or sometimes lying down in certain positions. I now can't stand up for more than like 15-30 minutes without the pain progressively getting worse. Especially standing still like in a line or things like that.
Some walking is okay, but again if it is more than for like 30 minutes the pain gets worse. Also bending down, trying to get up off the floor, climbing stairs, and picking up stuff like 25+ pounds repetitively are a problem. I go in for a CT scan in August to see how the fusion looks. Probably nothing else they can do on their end to improve things.
My fusion in my neck is better, but also has some issues. I can't turn my head quite as much as I used to and looking up and down is uncomfortable. I can't sit with my head tilted down very long or lay on my pillow wrong or I start getting a bad headache.
My activity level has suffered drastically from the fusions. I don't do near as much as I used to. No more amusement park rides. I probably can't bowl anymore (something I used to love to go do). Long drives are an issue now. We use to go on long walks and that is out now. Spend most of my time just sitting on my couch (forced to become a couch potato) or laying in bed.
I have been off from work going on 2 years now because of the different treatments and surgeries. With them making me try every imaginable fix before having both surgeries, it ended up milking the situation out for much longer. I had a really physical job that I can no longer do now. I've been on long term disability, but it will be running out in about 3 months. The disability insurance place made me fill out paperwork for social security but it was denied and they are going to appeal it. So I'm not sure what I will be doing after those 3 months are over.
Everybody is different and my case might be more extreme than others. My doctor diagnosed me with degenerative disc disease and that might be making things worse. I never had much luck with injections and my discectomy was only a short term fix. Maybe if I had a less physical job it might have been fine at that point and no fusion would have been necessary. Even with the way things are now I would still do it all over again. The nerve pain was so excruciatingly bad that I had no choice and not being able to do as much is better than not being able to do anything.
The one thing I wish I would have done is spent these 2 years doing schooling at home. Then maybe I could have gotten something useful accomplished from the time off. Might have opened up other possibilities. Of course I did nothing and just figured it would fix the problem enough to go back to my normal work. I'd say have the procedure done and with your age you might recover better with less limitations on your life, but plan on a worse case scenario that you might have to totally change your work and home life. Good luck to you on whatever you decide on.
