I'd get her on Blood Cleansing herbs (Meaning Burdock Root and Red Clover Tops), and Hydrangea Root tea to get the muscle pain down.
She will need to get/keep her bowels open, and it might be good to start with a coffee enema if possible, if not, then get a bottle of Sunsweet Prune juice from the grocery, and have her chug a large glass of it, then stay pretty close to the powder room for a few hours.
Something's having trouble moving out of her system or this wouldn't be happening.
You can alternate pots of the following herb teas (Health food store):
1 pot of Burdock Root & Red Clover tea, then 1 pot of Hydrangea Root tea.
She should drink as much of the teas as she can get down in a day; Neither of them will hurt her; You are likely to see improvement at the end of the first day.
