Special prayer for Liz please

Liz has become very unwell indeed and stands in need of much prayer. I have never seen her so ill before. She has a sudden and severe version of reactive arthritis, formerly known as Reiter's syndrome. It has developed suddenly in her body as a response to an unknown infection, causing cross-reactivity. She is being looked after by two specialists but has thus far not responded to any medication. She is weakened, has much pain and has limited mobility. She will apparently need a long period of treatment over many months. Please pray.
