Outbreak patterns tend to be an individualized thing. Some people who have herpes never have an OB, others have them a couple times a month while others seem to always be in OB mode.
Everyone is different but I have personally found that lifestyle choices, diet and nutrition are the main reason for my OB's. When I avoid acidic foods, sugar, alcohol, eat raw garlic, and take my Linus Pauling influenced homemade ascorbate, they are viritually non-existent.
Anyway, the OB cycle usually goes like this:
pre-blister patch, can be redish and itchy
blisters appear which can break or stay intact
tiny dark red/sometimes blackish scabs appear where blisters were
they heal and skin looks normal
The whole thing usually comes and goes in around a week for me, sooner if I take preventative nutritional actions immediately.
I don't recall every seeing anything I would call 'brown', but there seem to be a bunch of different mutations of HSV2 out there and everyone has different skin.
Anything is possible in this world, but I have yet to encounter anyone here or elsewhere who has legitimately claimed to be 'cured' of HSV meaning getting the blood test after a particular therapy and testing negative. There are many who have found treatments/regiments which cause the virus to remain essentially dormant.
In my opinon, this is the best you can hope for right now.
Not sure if the urine therapy is working as what you describe seems to sound like a normal cycle of an outbreak. I would suggest not using the urine once and seeing if the blisters leave any quicker. Most naturopaths I have encountered view urea as a relatively benign substance to treat HSV compared to other herbs and methods.
