Re: Help with meaning of diag.
I'm not qualified to comment, certainly not to diagnose.
But, Moderately severe LEFT foraminal stenosis At C6-C7 is consistent with left shoulder, arm and hand pain and numbness. Forminal stenosis is the narrowing of where the nerve root comes out of the vertebrae towards the left shoulder. It can cause pressure and possibly damage to the nerve. "Moderately severe" generally means it is significant and may or may not indicate a need for surgery.
Disc osteophyte complex producing a ventral extradural defect at c6 c7 can refer to bulging or some herniation of disc possibly caused by arthritic type bone growths. This contributes to the forminal stenosis.
Increased T2 is just an observation that most probably means nothing, but might.
minimal central canal stenosis with 9mm is okay and nothing spinal in the MRI seems to account for his problems walking.
This might be a side effect of the neurontin. When I was taking it, I had very poor balancing walking. DO NOT stop taking the neurontin except under a doctors guidance. Depending upon what strength and how long he has been taking it, he will need to slowly work off it.
Ask for a referral to a pain mgmt dr. Better meds and/or cervical injections, etc. might help significantly. It sounds like your husbands pain is in a 7-8 range. Good Pain mgmt should be able to get it down to 4-5.
Good Luck. I'm 2.5 years sleeping in a recliner, now an expensive zero gravity power model.
