Herniated cervical disc and mtb'ing

[7rider]

Hi all.
Brief history:
I've been having arm and upper back pain since late-September. It's worse when I ride my bike or use the computer. Knots through my traps and major pain in triceps, tingling at the ulner nerve and up into my wrist, thumb, index, and middle fingers.
I'd been seeing my chiro for some active release therapy, without much relief. So I went to see my MD who put me on muscle relaxers without much relief. So I went to see a orthopedic guy who x-rayed me (poker straight neck, but otherwise normal). He put me on prednisone for 2 weeks without much relief. Ortho orders nerve conduction test for carpal tunnel syndrome. Normal. Ortho orders an MRI. Lo and behold "multilevel degenerative disc disease." Bulging in C3-4 and C4-5 and a herniation in C5-6. Severe stenosis (narrowing) of the opening for the nerve.
Source of the ouch found.
So I'm on daily traction with my chiro until I get my "home kit" and can hang myself in the comfort of my own home. Ortho said "no restrictions" but I've been avoiding mountainbiking - I road bike rarely lately and am feeling it in the cardio and on the scale! So far, it still hurts my arm when I ride, so rides are short. Chiro strongly advices against mtb'ing at this point and as for skiing says "no bumps" - which is fine, as I hate moguls - and (helpfully) "Trees are okay - just don't hit them!"
But....
what are the chances of my EVER going mountainbiking again? I mean - nothing crazy, just riding some nice singletrack, maybe over a small log or rock or two. I don't do crazy, but I don't want to ride my dualie on a bikepath, either.
Have any of you had a herniated disc and continued to mtb? I don't want to risk long-term damage. Ortho said it won't heal, per se, but I can go to an asymptomatic state. But would mtb'ing wreck that?
Advice, words of wisdom are welcome!
Thanks....
