I feel for you; clearly your health and lifestyle are seriously affected by your neuralgia. And certainly there are plenty of stories like yours, i.e. people with neuralgia symptoms that they (and their doctors) believe are due to HSV-2. And they may be right. However, no credible research has proved that the one causes the other. A quarter of the population has HSV-2 and some people have unexplained neuralgia, so there are bound to be people with both problems, simply on a random basis.
Assuming you had a positive viral culture for HSV-2 somewhere along the line (when you were having overt herpes outbreaks), or if your recent positive blood test for HSV-2 was with a modern, type-specific test, you can be certain you are infected. (A positive blood test does not indicate only that the person was "exposed". It proves s/he is infected with the virus.) So I see no need for additional testing. However, if didn't have a positive culture and you're not sure whether a truly type-specific test was done (e.g., the HerpeSelect test), you should ask your provider about the possible need for repeat testing. (If in doubt about this or to learn more about HSV antibody testing, search the STD Forum threads for "herpes diagnosis" and "HerpeSelect test".)
The death of Steve Sacks, a close friend, indeed was a terrible blow to everyone in the herpes field.

Wow! Sad to say, I was relieved to read your post. I was infected with HSV2 about 13 years ago. My first two outbreaks resulted in meningitis and 2 hospitalizations within one year. After the second outbreak, I began to develop neuralgia symptoms. None of my doctors seemed to think there was anything to treat. I was also diagnosed with hypogammaglobulinemia, and went on IVIG treatment. My pain symptoms worsened until I couldn't put my left foot on the floor. I then saw a neurologist who began to treat me with neurontin, etc. I am much better now, but I take a lot of meds in order to function. I've found a balance between the amount of pain I can tolerate, and the amount of meds I can tolerate. Neither is perfect; I'm always in pain, and I take more medication than I would like. But it is the best I can do for now. The whole left side of my body has been affected, where originally, the pain was in the back of my leg and foot. I have pain from my left eye, left arm, hand, leg, etc. I also have decreased sensitivity on the surface of my skin on my left side, and areas of total numbness.
I can tell you that I have found articles linking PHN and hypogammaglobulinemia, The suggestion was that hypogammaglobulinemia may result in more severe, prolonged, and frequent herpes outbreaks, thus leading to increased incidents of PHN. Most of the doctors I've been to are of the belief that I might have a zoster (shingles) infection, in addition to HSV2. They have insisted that HSV2 does not cause the type of PHN I have experienced. It's hard to know what to believe.
Regarding IVIG treatment, one year may not have been sufficient. I still had abnormal tests (lymphocyte proliferation) after one year. After four years, my tests came back consistently normal. I recently had another battery done. 10 years after my last IVIG treatment, my immune system functions normally. That has not helped my pain level, or changed my outbreaks, but I am certainly healthier, and do not get the kinds of illnesses I had previously been prone to (pneumonia, throat infections, ulcers).
I do know what you mean when you say that this illness, the PHN in particular, has become your life. I often feel that way. It's hard to function properly when taking pain meds. I don't know if this will help you, but what I've done is accepted that I will live with a modicum of pain at all times, and that I will only medicate myself to achieve a lessening of pain. I no longer strive for elimination of pain. I do all I can to maintain mobility. Yoga and strength training have helped a lot. Doing yoga in a hot room is particularly helpful. Cold makes me miserable. Very few people understand what this is like. I'm so glad I'm not the only one!
