Several weeks ago, I treated myself with over the counter meds for what I thought was a nasty yeast infection. Then, the following week, my husband complained of itching and a red rash in and on his genitals, but he didn't do/take anything and it went away. Now, I have what I think is a yeast infection again. Could we be passing a yeast infection or something else back and forth? What can I do to make this go away? I have endometriosis. Am I more likely to just get lots of yeast infections?
