I've been having recurring thrush for the past few years. I've used canesten several times, but it has not permanently cured the problem. There is no itching involved, only a milky white discharge. I've been to my GP, who took a vaginal swab, but nothing abnormal was found. It has been affecting my husband in the sense that he develops the most terrible rash on and around his private parts if he does not shower immediately after we've been intimate. Is this normal, and what can we both use to alleviate this problem?
