Denac,
wellcome on board!!
First of all - very sorry you are having such a problem. I would certainly discuss with my Doctor my options.
I had my 2level fusion 17 month ago and i am still on disability. 6 month after my surgery i practically could not walk or move much - that how much pain i was in. I am still in pain, but i get a normal days now also, although some days i can't get up from bed.
I also have anoter level broke on top of my surgery and the lowest also. But my Doctor at HSS told me that if we can buy some time - we will do it since more spinal surgeries we have - weaker our spines become.
YOu can read a lot of material if you go through all the treads about second surgeries; removal of hardware is very "hot" topic; i was told my hardware would be removed only if i have anoter 3 level surgery they don't do it just to remove hardware.
All depends what exactly is wrong in your case - they have to find out. Just want to tell you that recovery after spinal surgeries are very tough and we all get ups and downs way long after the surgery. 6 month is still a short time. But i definatelly would discuss this matter with my Doctor and if you need - you can go for second opinion.
Best wishes on your recovery.
