Hobbying:
1. Strap the arm down.
2. Put a sad dog expression on your face
3. Ask her to cowgirl up (spurs off).
Driving:
If you can keep the bad arm off the wheel (strap it down), go for it. But driving is so ingrained that if you have the bad arm on the wheel, you're liable to do something that will put you back on the pain meds. Gladiator is absolutely correct on the pain meds and we both agree on the rehab. By the way, the meds will also pretty much ruin playing with any gal.
