Jimking,
This is wonderful news

I know my swollen knees and legs feel so much better when they relax and I can move them.
The prednisone does cause a quick reverse in the inflammatory process, and also an upbeat mood. However, it also can bring weight gain because of the water retention by-product of the medication, and mood changes by a lower threshold of the anger emotion(when used for a prolonged period of time).
The Cymbalta assists in pain control and depression;specifically, increasing the hormones that bring an upbeat mood (seritonim,sp?)and lowers the pain signal processes (norepinephron,sp?); for example, neuropathy.
This is based upon research and my own life experience with Cymbalta and prednisone medications.
In any case, your wife has relief and that is what we all strive for..a break in the pain arena.
CHEERS!!!!!
