As you know, Valtrex is an antiviral medication used to treat chronic viral infections like HSV or Herpes Simplex Virus. But the symptoms you have described here are not likely to be the side effects of Valtrex. Anyway, in some people having Herpes, there occur symptoms like you told. In some people symptoms of herpes are more severe and may have painful nerve endings, swollen glands and itching. So, it is better to consult your doctor for further care and prescriptions. He can know the nature of your body and its immunity better than us. Hope my answer helps. Take care.
