hi again -
yea I had x-ray too before my post op visits - this way they can check to see how the fusion is healing/any bone growth and also the hardware.
I had so many fears that when I did something I shouldn't have that I messed up something - last year I had bad episodes of sitting up in bed, cross legged and would fall asleep and would fall off the bed!!! I was so worried on one fall as it was bad and I really thought I did something. went to ER and they did x-ray and said everything looked good. had appt with my pain doc and told him what happened - he said let's get MRI just to see if maybe I damaged other discs - he basically said my hardware was in place and would not budge ( unless real bad accident) and said it was sturdy. a surgeon said that with my single fusion the hardware was pretty stable about 4-6 months post op - you've had a bigger fusion and i'm sure most of it is pretty secure.
it could be that all your feelings are starting to heal and ur feeling your back differently (as you will always now) and you could have some muscle spasm.
are you still wearing a back brace? even though my surgery was in 2/08 I still wear my back brace just for the extra support.
please let us know how u are doing and what the surgeon says - take care - Joy
