I read your comments with great interest, i am on arimidex and have noticed over the past few weeks that my underneath is what you would call smelly, also have dark urine due to vitamins, have to change underwear as seems stained and smelly too. thought i had an infection but everything i have bought over the counter has made no difference. Perhaps this is due to the Arimidex and i should stop buying pessaries and such like now and accept it, perhaps it is something to do with the lack of oestrogen in our bodies.
