I wouldn't take a NSAIDs with a virus.
Here are some alternatives related to varicella, which could help. http://www.mothering.com/discussions...26&postcount=4
Topically, I'd probably do Epsom salt baths, perhaps some baking soda soaks, maybe some lavender essential oil, possibly coconut oil topically, might try calendula topically for comfort. Homeopathic apis for itching. Oatmeal baths. Maybe homeopathic Hypericum for nerve pain.
I'd recommend seeing a classical homeopath.
