Interestingly, there seems to be pretty sound evidence that Herpes Simplex Virus (HSV) infection is associated with the occurrence of rash and skin reactions (erythema multiforme).

In an earlier post, @Gingergrrl speculated that that the rash I had in response to Ampicillin could have been caused by some kind of active EBV infection (which may also cause the CFS). Ampicillin exanthema has been specifically tied to active EBV infection and mononucleosis.
But I have fairly low titers against EBV (all sorts). But I do have super-high titers against Herpes Simplex Virus 1 (IgG ">1:20,000", IgM negative).
Maybe the Herpes Simplex is causing the rash and also the CFS. But I have seen no study so far that ties HSV-1 specifically to antibiotics-induced rash.
But next thing I'll probably do is try another course of Valacyclovir directed against HSV-1 plus some anti-HSV-1 supplements (L-Lysin, propolis) and a low-arginine diet.
