Training thru injury?

So a couple months ago, a new guy got me in a can opener and before I could escape my hips, he stacked me. Felt a pop and pain in my neck, but brushed it off and finished the roll. Shortly after, was having pain in my shoulder and arm.
Being a jack ash, I continued training 6 days a week. It got to the point that I couldn't stand for more than 15 minutes without my arm going numb.

After 3 months I finally got my neck x-rayed. I have sclerosis and osteophyte on my C5 and C6 vertebrae. I'm waiting on my appointment with an orthopedic to see about treatment, but my doctor said to lay off all physical activity for now.

I've looked on the internet, but can't find anything from grapplers with neck injuries.

So, being a jack ash, I've continued to go to jitsu, but I'm only doing drills and very light rolling.

I know the 'logical' thing would be to listen to my doctor, but he's just general practice and that's the default answer for law suit purposes. I have 2 competitions coming up in the next 5 weeks, and I'm terrified of ceasing all training.

Seriouly, I in vision myself having to start from scratch if I miss a few weeks of training.
