Thanks girls. I forgot to mention, she has also seen a Chinese Medicine Practitioner who has given her a 'tincture' - I presume something like a homeopathic treatment? - but has been taking this for a couple of months with no change. Another friend suggested she go back and request acupuncture or some 'stronger' herbs and she is planning to do this soon. Just really fishing to see if anyone knows of specific things she should be asking about. She wants answers... but for now all she can get is a "maybe you could try...". I realise that the body is a subtle and complex thing and she may not get to the bottom of exactly what's happening, but I can completely understand her wanting to know WHY and to therefore have a specific treatment approach.
