In regards to Chinese Medicine (TCM I assume) I have had great success with a general 'tonifying' of the blood. My acupuncturist has also said that the condition of 'dampness' in my body has led to OB's. We focus a lot on tonifying the blood and removing dampness.
It is possible that you got Herpes in your body and did not realize it. It has definitely happened to some although it is considered rare to get the disease and not have a monsterous huge first outbreak. This is the first time the virus is introduced to our bodies and we do not have any immunity to it.
Honestly, though, what you have described sounds a bit like some of my Outbreak. A patch will occur on my penis/pelvic region and not develop into full blisters before subsiding. This is usually because I immediately start my immune_boosting protocol right when the itching starts.
In most other OB's though, there is a cycle of: itching, patch devlops, blisters develop, blisters subside, dark red dots/scabs where blisters occur. red dots subside, etc.
If this cycle HAS NEVER happened to you on either area of your body, it seems that it may not be Herpes.
It is unfortunate that you cannot get adequately examined! Keep trying to find someone who can get you the 'blood test for HSV'!
