I’m curious; did your doctor prescribe the avetlox antibiotic for Candida?,
The inside of the lips sound like it could be Candida, but of course I can’t see it so I really can’t tell. But the fact of there being no burning, bleeding, or itching would make me thing it’s Candida. I’ve never known of bleeding to occur with a Candida spot, and I believe it isn’t often that the inside of the mouth would burn or itch unless it grows a lot worse. The genital problem could also be Candida.
More importantly, try to pay attention to when these areas seem to be at their worse as compared with what you are eating at any time.
The fact that your wife has the same lip problem is no big surprise. A husband and wife often share the same diet and lifestyle, more or less.
