I had a mastectomy last October for a grade 3 breast tumour and also 4 lymph nodes removed. One was cancerous and the rest were clear. I started anastrozole in December and at first all seemed fine. However by January I started to get pain in my legs and then my lower back. Now most joints are painful and also bones. I am never pain free as even strong painkillers don't take pain away only dulling it. I have stopped the anastrozole to see if things improve but no luck so far. I would appreciate any advice on helping pain and also an indication of how long before things might improve.
