hi, I was diagnosed with stage 1 breast cancer in April had lumpectomy in May, results on lymph nodes in June which were all clear, started radiotherapy in July and finished in August. I have been on letrazole since April/May and was coping ok on them, I have just come back from 10 days in Tenerife and have been in so much pain since, my joints are really stiff and painful. I talk to another lady on here privately and mentioned this and got the two packets of letrazole out of the cupboard to look at them and realised they are two different makes, the make I am taking atm is different to the ones I have always been on. Does anybody think it could be the two different makes that are making me so stiff or is it just a coincidence. Any reply would be greatly appreciated.
