Oh - I forgot to mention that the other thing that has really helped was the Graston Technique. I don't know where your friend lives in the UK but if she can find a GT practitioner that might be worth a try. (for those of you who don't know, this is a soft tissue techique which is performed with stainless steel instruments) I have a patient who had a dreadful chronic bursitis, had surgery on it, but only really got sorted out with GT.
