Hi and welcome to HCM.Thanks for the query.
of course it can reoccur. herpes is sometimes dormant for entire life and tehre are phgases of exacerbation especailly after some stress
or infection. so this could be herpes zoster
infection again. of course any other infections can be considered too so try with antiherpetic creams first and if this isnt helpful you should consult your doctor
Wish you good health. Regards
