Some people infected by the virus will have a recurrent infection around two or three times a year, while others might have one initial outbreak and never have another.
In the former case, you will have repeated outbreaks, starting as a tingling or burning sensation, soon followed by blisters that begin to ooze.
The virus reactivates around the same spot every time. You can expect to develop blisters in the same place as previous outbreaks.
The severity of outbreaks generally lessens over time with a reactivation of the virus tending to decrease in people over the age of 35 years. You can also expect less severe symptoms at each recurrence.
