Hmmm... those are pretty grim prospects being pointed out.

I wouldn't buy into it, not only do you have the advantage of being a physio, you sound young enough and motivated enough to manage the problem.

Use your critical reasoning skills to help guide your self-Rx.
If something causes problems/discomfort its your body telling you to take a step back, write up a management program and stick to it.
Begin with low intensity exercise. I would begin with a program that you complete every single day. Best in the morning to set the pace for the day ahead. Be concerned about functional ergonomics and muscle balance.
Add in strength exercises, higher the intensity the more infrequent the program need be. Again work on optimizing your 'new' biomechanics.
No grim outcomes here, only hard work and results.
