I've tried a variety of creams as well, doctors on visual exam believe its fungal, but the medications don't really seem to effect it, i'm in the same situation as you with mostly redness and irritation going on since August and so far no positive result on any of my tests. Plenty of people have dismissed this as herpes, but I have reasonable suspicions to believe this is herpes-the girl I was seeing had a red blister on her lip which she told me was from a sunburn but most likely it was a cold sore because it certainly looked like one. Trying to keep a open mind though on other possibility's because other things can mimic herpes in appearance and symptoms like intertrigo, staph infections and fungal, and those are known to cause long term irritation till they are treated properly, I'm constantly seeing my doctor about this and he for sure doesn't believe this is something that I'm making up, the skin anomalies are always present upon my visits and he is open to the idea of this being herpes as he has seen similar unusual cases of herpes before. Anyways if I ever get a proper diagnoses I keep you updated.
