Yes, I think it is Shingles
. Your nerve pain
due to herniated Disc
is not related to your Shingles. Your history of taking Valtrx suggests that you had Shingles in past. Whenever you see any first symptoms of Shingles, you must start immediately Valtrex
in full doses that is 1GM three times in a day for seven days. if it recurs in short interval, then you can take 500mg once in a day for 1 month.
Take good care.
