Hey, sorry I'm late for this - I never know which THREAD to check. Anyway TN and shingles. Yes Ma'am - trigeminal pain after a bout of shingles is real. That is only one of the causes of my trigeminal pain - but my MD gave me a big bottle of Valtrex 1 gram and I take one tablet at the first sign of an "outbreak". I haven't had a real break out of shingles in two years on this regmine. I hope this helps. Janet
