Rich,
That is a mess to be in. Let's focus first on getting your wife healed and ask God's intervention to illuminate the cause of her infection so it can be treated correctly.
Having had impingement surgery myself in march, lost insur. in May... I've had to do a home program to keep my arm functioning...you might ask the PT to give you a host of home exercises and really do your diligence on your own so it doesn't "freeze" on you! It's hard...but most will help with a home program... with so much hanging over you, it's hard to do those bloody painful exercises when everything else sucks, too....but it's worth it!
Keep the Son in your eyes. Prayers follow daily!
