You could try getting Genferon suppositories that you buy from Russia. They are used boost interleukins and someone I know was using them and it was helping a lot with her neuritis. She gets it from genital HSV1 and doesn't get outbreaks, just the tingling, itching, nerve pain. She is planning on also using the Herpavac vaccine next from Russia. Ever since she got the chickenpox vaccine she hasn't had any outbreaks, just this neuritis/neuralgia.
For me, I've been taking LDN (Low Dose Naltrexone) which modulates my immune system and has greatly reduced my daily symptoms. During the day I get practically no symptoms for last 2 weeks, but in the evenings I get some mild irritation. LDN is a prescription which I get from a naturopath. It is much safer than the antivirals and can have many benefits. I am now taking 2mg a day. I started at 0.5mg. I will keep increasing it slowly until hopefully all my symptoms disappear. Some have said this has happened for them who have hsv1 and it also benefits hsv2, like me. Check out this website to learn more.
