May 22, 2016 (Completely spontaneously resolved in 7 to 8 days time).


Treatment with indifferent (zinc oxide and zinc sulfate), anesthetic, or antiviral cream has a small favourable effect on the duration of the symptoms, if applied promptly. This is also the case with oral antiviral medication.


Effective antiviral medications include acyclovir and penciclovir, which can speed healing by as much as 10%.
