Rotator cuff tear, fractured wrist

I have a rotator cuff tear on my right arm and a fractured wrist on my left wrist. I've been in pain for about 8 months and barely found out with MRI results. All this time Dr. told me it was a shoulder strain or impingement but my last Dr ordered the mri and i finally know whats wrong with me. I will have surgery on my shoulder in April so I will be off the pole for a while. As far as my wrist it is keinbock's disease where the wrist bone dies because of bloody supply and it fractures. I have to immobilize it for 3 months. I need help. I'm in search of fun workouts I can do before I go insane. Any tips would be helpful. Stretching, yoga, cardio, aerial yoga without using my arms, etc.
