I am waiting to see an orthopedic surgeon on Dec. 13 to determine if surgery is needed. My symptoms are numbness, tingling and pain in my right arm. MRI report conclusion says:

1) Cervical disc degeneration with bony spondylotic ridging at C4-5 and C5-6 levels. Bony spurring produces moderate central spinal stenoiss at both of these levels with broad-based ventral cord effacement. At c5-6 the mdiline saggital diameter of the canal is narrowed to about 8 mm. The c4-5 midline sagittal daimter of the canal is narrowed to about 7 mm.

2. There is associated bilateral foraminal stenosis at c4-5 and c5-6 levels as described.

3. There is a small central herniation of the c3-4 disc, which focally indents the thecal sac in the midline and causes a mild degree of central stenosis. Canal to about 8 or 9 mm.

I am concerned about how active I can be. I like to ride my bike and motorcycle, as well as exercise with hand weights, etc.

Thanks.

There are two separate concerns here. The first is the central canal stenosis at C4-6. You mention no myelopathy symptoms (imbalance, loss of fine motor control, etc- see section on myelopathy on the website). The danger is then a fall onto your head which causes your neck to bend far backwards. The action will substantially narrow the central canal and could pinch the cord causing a central cord syndrome (see website).

The other problem is foraminal stenosis (narrowing of the exiting nerve hole). This condition is most likely causing your arm and hand symptoms. Controlled exercise (gym or non-wheeled exercises) are generally safe. The greater your speed or the more potential for imbalance (biking or motorcycling) the greater the risk.
