Scalp Burning, Itching, Sores Oh My!

I have Post-Herpetic, Occipital, Bi-Lateral and Atypical TN.  At least I have all of those symptoms!  I have been diagnosed as Post-Herpetic but it goes all over the place, mostly my eyes.  Ever since last summer when my occipital neuralgia was really bad (migranes all over my head), I have had scalp problems.  Burning, itching, sore spots, and sores.  I had ALOT of chicken pox scabs on my scalp and it almost feels like when I did have chicken pox.  It all comes and goes.  Anyone else have scalp problems like this, with or without post-herpetic TN?
