I haven't experienced this, but have you considered going on suppressive therapy to help prevent this? It sounds miserable, and maybe taking valtrex every day would help.
It wouldn't treat the neuralgia you have, if that's lingering, but it could help prevent further issues.
Or, if you don't want to take it daily, if there is a pattern to the outbreaks, you could take the valtrex for the 5-7 days prior to the outbreak and perhaps stop it.
I hope you see some improvement. If the neuralgia doesn't improve, don't hesitate to see a neurologist.
