Hang in there. Neck/back injuries take a long time to heal and yeah, may be be even chronic. However; you can get through this. It's like one step forward, two steps back. Don't give up and give your body time to heal. Easier said than done, I know. If it hurts stop.

If you need to see other docs, do so and know your options. Get the help you need.

With neck/back injuries, have you thought of a recumbent if needed? I've ridden a couple and enjoyed them. My back is bad and sometimes I think one would be perfect. Was drooling over one at the LBS today. Yes, they are totally different, but I hate for you to think you'll never ride a bike again.

Thinking good thoughts and ((((HUGS)))).
