Tamoxifen & itchiness

I've been reading the posts about Tamoxifen - thanks as always for your great insights. I've been on it since June and apart from hot flushes every night, haven't noticed any other major side effects....except in the past week I've suddenly developed this awful vaginal itch which is driving me crazy.....
Has anybody had anything similar and if so what do you do to relieve it??
Thanks
